V4L/DVB (7556): em28xx: fix locking on vidioc_s_fmt_cap Currently, vidioc_s_fmt_cap is allowed even if streaming is running on some other fh. This is likely to cause issues. Block use of vidioc_s_fmt_cap if someone else has claimed access to the device. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
