Subject: V4L/DVB (5869): Add check for valid control ID to v4l2_ctrl_next.
X-Git-Tag: v2.6.23-rc1~193^2~3

V4L/DVB (5869): Add check for valid control ID to v4l2_ctrl_next.

If v4l2_ctrl_next is called without the V4L2_CTRL_FLAG_NEXT_CTRL then it
should check whether the passed control ID is valid and return 0 if it
isn't. Otherwise a for-loop over the control IDs will never end.
