The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

The current hdpvr code kmalloc's a new buffer for every i2c read and
write. Rather than do that, lets allocate a buffer in the driver's
device struct and just use that every time.
The size I've chosen for the buffer is the maximum size I could
ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit
of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up
to 128).
Note that this might also remedy user reports of very sluggish behavior
of IR receive with hdpvr hardware.

A number of things going on here, but the end result is that the IR part
on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or
lirc_zilog.
First up, there are some conditional build fixes that come into play
whether i2c is built-in or modular. Second, we're swapping out
i2c_new_probed_device() for i2c_new_device(), as in my testing, probing
always fails, but we *know* that all hdpvr devices have a z8 chip at
0x70 and 0x71. Third, we're poking at an i2c address directly without a
client, and writing some magic bits to actually turn on this IR part
(this could use some improvement in the future). Fourth, some of the
i2c_adapter storage has been reworked, as the existing implementation
used to lead to an oops following i2c changes c. 2.6.31.
Earlier editions of this patch have been floating around the 'net for a
while, including being patched into Fedora kernels, and they *do* work.
This specific version isn't yet tested, beyond loading ir-kbd-i2c and
confirming that it does bind to the RX address of the hdpvr.

Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced
after it was freed.
Normally the i2c adapter is removed before this function is called. Removing
the adapter will also unregister all subdevs on that adapter, so generally
v4l2_device_unregister has nothing to do. However, in the case of a platform
i2c bus that bus is generally not freed.
In that case, after freeing the i2c subdevice the code will fall into the
second block when it tests if the subdev is a SPI device. But by that time
the subdev is already freed and the kernel oopses.
The fix is trivial: continue with the loop after freeing the i2c or spi
subdevice.

My initial thinking was that we should default to mouse mode, so people

but a lot of systems where a remote is useful automatically log in a

remote and don't see any feedback. Plus, first and foremost, its a
remote, so lets default to being a remote, and only toggle into mouse

Hi,
While reading
drivers/media/video/tlg2300/pd-video.c::alloc_bulk_urbs_generic() I
noticed that
- We don't free the memory allocated to 'urb' if the call to
usb_alloc_coherent() fails.
- If the 'num' argument to the function is ever <= 0 we'll return an
uninitialized variable 'i' to the caller.
The following patch addresses both of the above by a) calling
usb_free_urb() when usb_alloc_coherent() fails and by explicitly
initializing 'i' to zero.
I also moved the variables 'mem' and 'urb' inside the for loop. This does
not actually make any difference, it just seemed more correct to me to let
variables exist only in the innermost scope they are used.

Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.
It is expected that in the future open and close ops will also be added.

However, due to a trick at mb86a20s, it will later initialize properly:

This is hacky and ugly. However, I coldn't find any easy way to fix it.
A proper fix would be to have a resource locking schema, used by both
V4L and DVB parts that would block access to analog registers while
digital registers are in use, but this will probably put tda829x into
a dead lock.

There were some issues at tda8290 that were preventing this device
to work. Now that those fixes were fixed, we can enable analog
mode.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
Due to a hard to track bug between tda829x/tda18271/saa7134, tda829x
wants to go to analog mode during DVB initialization, causing some
I2C errors.
The analog failure doesn't cause any harm, as the device were already
properly initialized in analog mode. However, the failure at the digital
mode causes the frontend mb86a20s to not initialize. Fortunately, at
least on my tests, it was possible to detect that the device is a
mb86a20s before the failure.
What happens is that tda8290 is a very bad boy: during DVB setup, it
keeps insisting to call tda18271 analog_set_params, that calls
tune_agc code. The tune_agc code calls saa7134 driver, changing the
value of GPIO 27, switching from digital to analog mode and disabling
the access to mb86a20s, as, on Kworld SBTVD, the same GPIO used
to switch the hardware AGC mode seems to be used to enable the I2C
switch that allows access to the frontend (mb86a20s).
So, a call to analog_set_params ultimately disables the access to
the frontend, and causes a failure at the init frontend logic.
This patch is a workaround for this issue: it simply checks if the
frontend init had any failure. If so, it will init the frontend when
some DTV application will try to set DVB mode.
Even being a hack for Kworld SBTVD to work, and assumning that we could
teach tda8290 to be a good boy, this is actually an improvement at the
frontend driver, as it will be more reliable to initialization failures.

Looking at the windows inf file, for usb ids with a sensor type where probing

needed for all bridge variants with a usb id indicating this sensor type.
So do the probing to determine the actual sensor type for types where the

If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and

soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.
The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.
This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

Both we and the windows driver make no sensor specific differences
(with some exceptions) for different sonixj bridge types. Thus if a
sn9c105 bridge has been successfully tested with a sensor, the same
sensor can be successfully used with a sn9c120 bridge too.
Using this knowledge we can move over most usb-ids too the sonixj
driver when both are compiled.

Before this patch we were not setting the memory type to GSPCA_MEMORY_NO
when the buffers were released by the app doing a reqbufs 0. Nor would
the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file
already is NULL on device close because of the reqbufs 0. This caused the
following problem:
-app1 does reqbufs USERPTR for 4 buffers
-app1 does reqbufs USERPTR for 0 buffers
-app2 tries to do reqbufs MMAP for 4 buffers
fails because gspca_dev->memory still is USERPTR
Fixing this also allows an app to switch memory type's by unrequesting
the buffers and re-requesting them of a different type.
This patch also moves the setting of gspca_dev->frsz and gscpa_dev->memory
to after alloc_frame succeeding, so that they are not changed when allocating
fails.

In commit 411674fd18 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.
If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.
The original commit message read as follows:
This change allows bttv to use tvaudio for this device. Since this device
has the same i2c address as the tda9874 we need to support both in the same
tvaudio driver. This makes it possible for tvaudio to detect which chip is
used. Originally the tda9875 was only available in the dedicated tda9875
driver, but that makes life very hard for bttv since loading tvaudio might
misdetect a tda9875 as a tda9874.
So there were good reasons for moving the tda9875 code into tvaudio.

There are two Adaptec cards defined there, but AVC-2010 doesn't have a

The v4l core sets the v4l2_input.capabilities field based on the supplied
v4l2_ioctl_ops. However, several drivers do a memset or memcpy of the v4l2_input
struct, thus overwriting that field incorrectly.
Either remove the memset (which is already done by the v4l core), or add the

A Hauppauge HVR 4000 is used on a School On Internet Asia (SOI Asia)
project in order to carry IP traffic over ULE. However, there is an
issue with high latency jitter.
My boss, Husni, identified the problem and provided a patch for it.
The default buffer size of 32 TS frames on cx88 causes the high latency,
so our deployment changes that to 6 TS frames. This patch made the
buffer size tunable, while keeping the default buffer size of 32 TS
frames unchanged.

those changes were never submitted upstream.
Also, there's no DocBook for its API, nor any upstream discussion.
So, better to remove it, on .39. If later needed, we may rescue it

Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since

Basically it emulates hardware with a learning and a non-learning

receivers). TX data that is sent is fed back as input on the
corresponding receiver, which allows for debugging of IR decoders,

When trying to create persistent device names for mceusb and streamzap

device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.

Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,

bttv_ir is more consistent with all other structs used in the same driver.
Also, clean up the struct to remove commented out members and the work_struct
which is unused.

pwc was starting streaming on /dev/video# open rather then on STREAM_ON. Now
that the v4l1 compat code is removed from the pwc driver there is no reason
left to do this. So this patch changes the pwc driver to delay starting
the isoc stream (and thus using valuable usb bandwidth) until the application
does a STREAM_ON

Remote keytables had different names all over the place. Part of the fault
is due to a bad naming when rc subsystem was created, but there were lots
of old names that were still here.
Use a common standard for everything.

The struct that describes a rc mapping had an weird and long name.
We should properly name it, to make easier for developers to work
with it, and to avoid confusion.
Basically, generated by this script:
for i in `find drivers/staging -type f -name *.[ch]` `find include/media -type f -name *.[ch]` `find drivers/media -type f -name *.[ch]`; do sed s,ir_scancode_table,rc_map,g <$i >a && mv a $i; done

(and manually fixed where needed)

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
- ir-core.h to rc-core.h
- IR_CORE to RC_CORE
- namespace inside rc-core.c/rc-core.h
To be consistent with the other changes.
No functional change on this patch.

Something weird happened with commit 740069e6e043403199dbe2b42256722fb814f6ae.
Instead of dong the right thing, it got somehow corrupted and reverted the
rc changes.
Thanks to David Härdeman for pointing me about the problem.
This patch should be merged with 740069e6e04 before sending upstream.

Convert the driver to use the dvb_attach macro to avoid the hard dependency
on the frontend drivers. The hard dependecy will result in loading a
number of unused frontends, and unwanted automatic dereferencing.
This fixes a bug where unloading the mantis driver will derefence any
attached frontend twice, which will cause an oops if the same frontend is
used by another driver.

After dvb-core has called mantis-fe->stop_feed(dvbdmxfeed)
the last time (count to zero), no data should ever be copied
with dvb_dmx_swfilter() by a tasklet: the target structure
might be in an unusable state. Caller of mantis_fe->stop_feed()
assumes that feeding is stopped after stop_feed() has been
called, ie. dvb_dmx_swfilter() isn't running, and won't be called.
There is a risk that dvb_dmx_swfilter() references freed resources
(memory or spinlocks or ???) causing instabilities. Thus
tasklet_disable(&mantis->tasklet) must be called inside of
mantis-fe->stop_feed(dvbdmxfeed) when necessary.
