[media] videobuf2-core: Add it to device-drivers DocBook
Most of the stuff at videobuf2-core are ok for adding it to DocBook. Two notes here: 1) As videobuf2-core will be soon be changed, better to not spend too much efforts right now, as things will change soon; 2) struct vb2_queue has a number of private elements that are documented. As Kernel nano documentation format handles "private:" arguments, we need to put them on a separate comment block or to remove. Keeping the comments is obviously better ;) Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Jonathan Corbet <corbet@lwn.net>
