It also make easier and faster to find buffer and plane from using the offset field. Change __find_plane_by_offset() prototype to return the video buffer itself rather than it index.

To know which entries of the bufs arrays are used a bitmap will be added in struct vb2_queue. That will also mean that the number of buffers will be computed given the number of bit set in this bitmap. To smoothly allow this evolution all drives must stop using directly num_buffers field from struct vb2_queue. Let do it in 4 steps: - Introduce vb2_get_num_buffers() helper - Rework how create_bufs first buffer index is computed - Rework all drivers to remove direct calls to queue num_buffers - Replace num_buffers by a bitmap.
