media: media videobuf2: Stop direct calls to queue num_buffers field
Use vb2_get_num_buffers() to avoid using queue num_buffers field directly. This allows us to change how the number of buffers is computed in the future. Fixes: d055a76c0065 ("media: core: Report the maximum possible number of buffers for the queue") Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com> Acked-by: Tomasz Figa <tfiga@chromium.org> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
