media: v4l2-ctrls: add change flag for when dimensions change
Add a new V4L2_EVENT_CTRL_CH_DIMENSIONS change flag that is issued when the dimensions of an array change as a result of a __v4l2_ctrl_modify_dimensions() call. This will inform userspace that there are new dimensions. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
