56a263aaa0 [media] cec: Kconfig cleanup
The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

a7b8e9a5b3 [media] em28xx: shed some light on video input formats
CbYCrY has been identified by looking into the tvp5150 driver and the

YUV formats have been verified with em2765 + ov2640 (VAD Laplace webcam).
RGB8 formats have been verified with em2710/em2820 + mt9v011 (Silvercrest
webcam 1.3mpix).
I also did some cross-checking with these two camera devices and 0x08-0x0b
are at least 16 bits per pixel formats on em2710/em2820, too, and
0x0c-0x0f are at least 8 bits per pixel formats on em2765, too.

85316cf8da [media] em28xx: don't treat device as webcam if an unknown sensor is detected
With an unknown sensor, norm_maxw() and norm_maxh() return 0 as max.
height and width values, which causes a devide by zero in size_to_scale().
Of course we could use speculative default values for unknown sensors,
but the chance that the device works at this resolution without any
driver/setup is very low and therefore not worth the efforts.
Instead, just don't treat the device as camera.
A message will then be printed to the log that the device isn't supported.

4d58443696 [media] em28xx: simplify ID-reading from Micron sensors
Use i2c_smbus_read_word_data() instead of i2c_master_send() and
i2c_master_recv() for reading the ID of Micorn sensors.

i2c_smbus_read_word_data() assumes that byes are in little-endian,
so, it uses:
	data->word = msgbuf1[0] | (msgbuf1[1] << 8);

However, Micron datasheet describes the ID as if they were read
in big-endian. So, we need to change the byte order in order to
match the ID number as described on their datasheets.

e7080d4471 [media] media/dvb-core: Race condition when writing to CAM
It started with a sporadic message in syslog: "CAM tried to send a
buffer larger than the ecount size" This message is not the fault
itself, but a consecutive fault, after a read error from the CAM. This
happens only on several CAMs, several hardware, and of course sporadic.

It is a consecutive fault, if the last read from the CAM did fail. I
guess this will not happen on all CAMs, but at least it did on mine.
There was a write error to the CAM and during the re-initialization
procedure, the CAM finished the last read, although it got a RS.

The write error to the CAM happened because a race condition between HC
write, checking DA and FR.

This patch added an additional check for DA(RE), just after checking FR.
It is important to read the CAMs status register again, to give the CAM
the necessary time for a proper reaction to HC. Please note the
description within the source code (patch below).

When fe_ops.read_status is called and no channel is tuned (yet), the
subsequent calls to get_lock_status() causes the kernel log to be filled
with

    drxk: Error -22 on get_lock_status

which either means a NULL pointer was passed for the p_lock_status var,
or neither QAM nor OFDM/DVBT operation mode are active. Instead of
filling the kernel log in the latter case, print out a message to the debug
level and return 0 (this isn't used in the calling drxk_get_stats() anyway).

c0746c1ad3 [media] tc358743: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
