media: uvcvideo: Fix clock param realtime setting
commit 3b35fc81e7ec552147a4fd843d0da0bbbe4ef253 upstream.
timestamps in v4l2 buffers returned to userspace are updated in
uvc_video_clock_update() which uses timestamps fetched from
uvc_video_clock_decode() by calling unconditionally ktime_get_ts().
Hence setting the module clock param to realtime has no effect before
this patch.
This has been tested with ffmpeg:
ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 30 -i /dev/video0 \
-f alsa -acodec pcm_s16le -ar 16000 -ac 1 -i default \
-c:v libx264 -preset ultrafast \
-c:a libfdk_aac \
out.mkv
and inspecting the v4l2 input starting timestamp.
