The copy logic assumes that the data width is multiple of two,
as this is needed in order to support YUYV.
There's no reason to force it to be 8-pixel aligned, as 2-pixel
alignment is enough.

The vim2m device is interesting to simulate a webcam. As most
sensors are arranged using bayer formats, the best is to support
to output data using those formats.
So, add support for them.
All 4 8-bit bayer formats tested with:
$ qvidcap -p &
$ v4l2-ctl --stream-mmap --stream-out-mmap --stream-to-host localhost --stream-lossless --stream-out-hor-speed 1 -v pixelformat=RGGB
It was tested also with GStreamer with:
$ gst-validate-1.0 filesrc location=some_video.mp4 ! qtdemux ! avdec_h264 ! videoconvert ! videoscale ! v4l2convert disable-passthrough=1 extra-controls="s,horizontal_flip=0,vertical_flip=0" ! bayer2rgb ! videoconvert ! xvimagesink
For all possible HFLIP/VFLIP values.

When an rc device is created, we do not know what key codes it will
support, since a new keymap might be loaded at some later point. So,
we set all keybit in the input device.
The uevent for the input device includes all the key codes, of which
there are now 768. This overflows the size of the uevent
(UEVENT_BUFFER_SIZE) and no event is generated.
Revert for now until we figure out a different solution.
This reverts commit fec225a043.

The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(),
and this makes this device's runtime PM usage count a negative value.
The ov7740_set_ctrl() tries to do something only if the device's runtime
PM usage counter is nonzero.
ov7740_set_ctrl()
{
if (!pm_runtime_get_if_in_use(&client->dev))
return 0;
<do something>;
pm_runtime_put(&client->dev);
return ret;
}
However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup()
while the runtime PM of this device is not yet enabled. In this case,
the pm_runtime_get_if_in_use() returns -EINVAL (!= 0).
Therefore we can't bail out of this function and the usage count is
decreased by pm_runtime_put() without increment.
This fixes this problem by enabling the runtime PM of this device before
v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called
when the runtime PM is enabled.

The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant
as this has been already checked at the start of the function and if
it's not that value then -ENOSYS is returned. Hence the sprintf can be
replaced by a simpler string copy.
