The name of the pvrusb2 module is not likely to ever change, and there
are plenty of other places where the name is directly coded, so there
is little utility in using a macro to infer the module name here. In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently. Yes I
know for many places we don't have to worry about that. But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver. I'm just removing a nicety that didn't have a lot of
value here to begin with.

Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw
internal API regarding i2c chip debug register access. However that
change failed to also update the corresponding function comment
describing the API. As driver maintained I never saw a request for an
ack on that change; there probably should have been one especially
since the manner in which this API operates was changed - its
interface is now entangled with a v4l specific struct and I would have
preferred to keep this API clear of moving-target v4l-isms such as

This patch adds the capability of selecting between 4 different inputs
on vivi driver. Input 0 is the normal color bar, while inputs 1-3 are
modified color bars.
This allows testing input selection on userspace applications and
serves as an implementation model for other drivers.
The current approach allows a maximum of 10 different inputs, since the
input name generator assumes that we need just one digit to present the
input. It shouldn't be hard to modify it to present a bigger name of
inputs, but, in fact, it doesn't make much sense of doing it for this
test driver.

=======================
The culprit in the trace is snd_pcm_action() which invokes a spin lock
which disables pre-emption which disables an IRQ which causes the
__might_sleep() function to fail the irqs_disabled() test. Since
pre-emption is enabled then it is safe to de-allocate the memory if
you first unlink each URB. In this instance you are safe since
pre-emption is disabled. If pre-emption and irqs are not disabled then
call usb_kill_urb(), else call usb_unlink_urb().

The driver was keeping a global array with an entry for each zoran device
probed. It was a leftover from when the driver didn't dynamically allocate
the driver data for each device.
There was only one use left, in the video device's ->open() method, looking
up the struct zoran for the opened device from the minor number. This can
be done better with video_get_drvdata().
Since zoran_num is now only used in the pci driver's ->probe() method, it
doesn't need to be an atomic_t and be static. There is a race if multiple
zoran cards could be probed at the same time, but currently the probe

As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:

(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':

cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'
With those configs:
CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m
After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.
What happens is that:
- cx88-i2c (part of cx8800) has some special rules if DVB;
- cx88-mpeg (cx8802 module) has also part of DVB init code;
- cx88-dvb has the rest of the dvb code;
- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.
So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.
Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.
While on this code, let's fix also a reported problem:

Not all architectures provide clear_user_page(), but clear_user_highpage()
is available everywhere at least via the compatibility inline function.
Is this the "trivial patch" that's required for these two drivers?

This patch (as1161) changes the interface to
usb_lock_device_for_reset(). The existing interface is apparently not
very clear, judging from the fact that several of its callers don't
use it correctly. The new interface always returns 0 for success and
it always requires the caller to unlock the device afterward.
The new routine will not return immediately if it is called while the
driver's probe method is running. Instead it will wait until the
probe is over and the device has been unlocked. This shouldn't cause
any problems; I don't know of any cases where drivers call
usb_lock_device_for_reset() during probe.

There are a number of drivers which set their i2c bus class to
I2C_CLASS_CAM_DIGITAL, however no chip driver actually checks for this
flag, so we might as well drop it now.

f_op->poll is the only vfs operation which is not allowed to sleep. It's
because poll and select implementation used task state to synchronize
against wake ups, which doesn't have to be the case anymore as wait/wake
interface can now use custom wake up functions. The non-sleep restriction
can be a bit tricky because ->poll is not called from an atomic context
and the result of accidentally sleeping in ->poll only shows up as
temporary busy looping when the timing is right or rather wrong.
This patch converts poll/select to use custom wake up function and use
separate triggered variable to synchronize against wake up events. The
only added overhead is an extra function call during wake up and
negligible.
This patch removes the one non-sleep exception from vfs locking rules and
is beneficial to userland filesystem implementations like FUSE, 9p or
peculiar fs like spufs as it's very difficult for those to implement
non-sleeping poll method.
While at it, make the following cosmetic changes to make poll.h and
select.c checkpatch friendly.
* s/type * symbol/type *symbol/ : three places in poll.h
* remove blank line before EXPORT_SYMBOL() : two places in select.c
Oleg: spotted missing barrier in poll_schedule_timeout()
Davide: spotted missing write barrier in pollwake()

The radio_release function of the BTTV driver is missing a call to
v4l2_prio_close. As a result, after the radio device has been opened at
least once (e.g., by HAL during bootup), v4l2_priority will never drop below
V4L2_PRIORITY_INTERACTIVE again. With the following patch against 2.6.28,
applications that run with V4L2_PRIORITY_BACKGROUND are able to open devices
again. Previous Linux versions are affected as well.

Some devices require different setups on struct_audio. Due to that, we
may need to change some fields at dev.adev during device probe. So, this
patch moves the dynamic memory allocation of adev at em28xx-alsa to the
dynamic allocation of struct em28xx dev that happens during device
probe.

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.
Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.
