2012-07-30[media] Documentation: Add newline at end-of-file to files lacking oneJesper Juhl
This patch simply adds a newline character at end-of-file to those files in Documentation/ that currently lack one. This is done for a few different reasons: A) It's rather annoying when you do "cat some_file.txt" that your prompt/cursor ends up at the end of the last line of output rather than on a new line. B) Some tools that process files line-by-line may get confused by the lack of a newline on the last line. C) The "\ No newline at end of file" line in diffs annoys me for some reason. So, let's just add the missing newline once and for all. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-07-30[media] vivi: remove pointless video_nr++Hans Verkuil
Remove the pointless video_nr++. It doesn't do anything useful and it has the unexpected side-effect of changing the video_nr module option, so cat /sys/module/vivi/parameters/video_nr gives a different value back then what was specified with modprobe.

V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT capability flags are left untouched and will be removed in future, after a transition period required for existing applications to be adapted to check only for V4L2_CAP_VIDEO_M2M.
