UVC makefile defines obj as:
obj-$(CONFIG_USB_VIDEO_CLASS) := uvcvideo.o
Instead of:
obj-$(CONFIG_USB_VIDEO_CLASS) += uvcvideo.oDue to that, if uvc is selected, all obj-y or obj-m that were added to
compilation were forget. This breaks a proper kernel build.Acked-by: Laurent Pinchart

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).Signed-off-by: Arjan van de Ven

VIDIOC_ENUMSTD did not return all the PAL/SECAM/NTSC variants: it just returned
one single PAL/SECAM/NTSC standard without separate entries for the trickier
standards like NTSC-JP.Changed the code so that it behaves better.
Also simplified the if/switch statements into a common standards lookup table.

cx18: Fix S-Video and Compsite input settings for the Yuan MPC718 per user
reports from Yuri Warczynski and
Brian Hope and enable the card entry. The tuner reset
GPIO pin is likely incorrect as the tuner firmware cannot be reloaded without a
reboot. It is likely the audio routing is done via GPIO which is not
implemented yet, as users report audio doesn't work for some inputs.Signed-off-by: Andy Walls

When an error occurs at firmware loading, sometimes, tda1004x stops answering.
Instead of reporting such error, attach code were assuming that the device were
answering an invalid ID (0xff). This can be seen when enabling debug options:tda1004x: tda1004x_read_byte: reg=0x0
tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5Now, instead of reporting an invalid ID, it will report the correct error:
tda10046: chip is not answering. Giving up.
