media: v4l2-ioctl.c: fix missing unlock in __video_do_ioctl()
If dev_debug was active, then the code could return without unlocking the core mutex. Replace the return with a 'goto unlock' to ensure proper unlocking. Fixes: 73a110623e7b ("v4l2-core: push taking ioctl mutex down to ioctl handler") Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
