Revert "[media] v4l2-dv-timings: fix a sparse warning"
Sparse got a fix for that. Also, it is suspected that reverting this patch might cause compilation breakages on userspace. So, revert it. This reverts commit 5c2cacc1028917168b0f7650008dceaa6f7e3fe2. Requested-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
