ee67674a77 [media] xc5000: always write at dmesg when it fails to upload firmware
On a normal condition, no errors should happen at xc5000
firmware upload is done. So, print at the dmesg if something
bad happens.

8604f3552b [media] xc5000: optimize firmware retry logic
Currently, firmware retry logic keeps reading from FS every
time during the retry logic. This is not needed. Instead,
only release the firmware read after success.

While here, make the non-debug messages less verbose, as it
only matters to the user if the firmware was successfully
loaded, or if some error happened.

2621c0b322 [media] xc5000: Don't try forever to load the firmware
With the current code, if something bad happens during the
firmware init process, the device will keep trying forever,
and removing it would cause an OOPS.

Instead, try only a limited amount of time. If not, fails.

32570579cb [media] ir-rc5-decoder: print where decoding fails
The IR dprintk message that prints a RC5 decoding failure
is not much helpful, as it doesn't tell on what bit the
error occurred.

Add such information, in order to make the debug message
more useful.

d24b69fc6b [media] rc-main: allow raw protocol drivers to restrict the allowed protos
On some hardware (au0828/au8522), the hardware is broken with
regards to the initial pulse detection. So, the driver needs to
produce a fake start pulse. That limits the acceptable protocols,
as it is not possible to produce a fake pulse that would cover
all supported protocols.

So, allow the driver to explicitly set the allowed protocols.

If the driver doesn't specify, keep the old behavior.

cfd0c77d08 [media] au0828: improve I2C speed
Commits 21dc61d3c0 and 7a1dd50b89 reduced the board I2C
speed to 20 MHz by default, due to a I2C stretch issue:
while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.

However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.

So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.

That happens because the frontend was disabled by .config, but the
si2165_attach void stub require those structs, and also the
drivers that call it.

9c9cb1fad8 [media] v4l2-ctrls: fix rounding calculation
Commit 958c7c7e65 ("[media] v4l2-ctrls: fix corner case in round-to-range code") broke
controls that use a negative range.

The cause was a s32/u32 mixup: ctrl->step is unsigned while all others are signed. So
the result type of the expression '(ctrl)->maximum - ((ctrl)->step / 2)' became unsigned,
making 'val >= (ctrl)->maximum - ((ctrl)->step / 2)' true, since '((u32)-128) > 128'
(if val = -128, maximum = 128 and step = 1).

So carefully cast (step / 2) to s32.

There was one cast of step to s32 where it should have been u32 because both offset and
step are unsigned, so casting to signed makes no sense there. You do need a cast to u32
there, because otherwise architectures that have no 64-bit division start complaining
(step is a u64).

5b8c8d4191 [media] mceusb: select default keytable based on vendor
Some vendors have their on keymap table that are used on
all (or almost all) models for that vendor.

So, instead of specifying the keymap table per USB ID,
let's use the Vendor ID's table by default.

At the end, this will mean less code to be added when newer
devices for those vendors are added.

Of course, if rc_map is specified per board, it takes
precedence.

3ab2512337 [media] af9035: override tuner for AVerMedia A835B devices
Tuner ID set into EEPROM is wrong, which causes driver to select
wrong tuner profile. That leads device non-working. Fix issue by
overriding known bad tuner IDs with suitable default value.

7b4eeed174 [media] vmalloc_sg: make sure all pages in vmalloc area are really DMA-ready
Patch originally written by Konrad. Rebased on current linux media tree.

Under Xen, vmalloc_32() isn't guaranteed to return pages which are really
under 4G in machine physical addresses (only in virtual pseudo-physical
addresses).  To work around this, implement a vmalloc variant which
allocates each page with dma_alloc_coherent() to guarantee that each
page is suitable for the device in question.

drx39xyj driver lacks resume support. Add support by changing
its fe ops init interface to detect the resume status by checking
fe exit flag and do the necessary initialization. With this change,
driver resume correctly in both dvb adapter is not in use and in use
by an application cases.

87cd0fa811 [media] media: dvb-core add new flag exit flag value for resume
Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.

Change em28xx_dvb_fini() to set fe exit flag to DVB_FE_DEVICE_REMOVED
when device is disconnected. em28xx maintains device disconnect status
in em28xx device. fe drivers will be able to now check the fe exit
status to avoid accessing the device, from their release interfaces
when called from disconnect path. This change depends on dvb-core
change that exports fe exit flag by moving it from fepriv to fe.
