ERROR: "v4l2_fh_release" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined! ERROR: "video_devdata" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined! ERROR: "__tracepoint_vb2_buf_done" [drivers/media/common/videobuf/videobuf2-core.ko] undefined! ERROR: "__tracepoint_vb2_dqbuf" [drivers/media/common/videobuf/videobuf2-core.ko] undefined! ERROR: "v4l_vb2q_enable_media_source" [drivers/media/common/videobuf/videobuf2-core.ko] undefined! We want to be able to build the core au0828 support without V4L2, so this makes the 'select' conditional on V4L2, and refines the dependencies in VIDEO_AU0828_V4L2 so it can only be enabled in the exact conditions that have VIDEOBUF2_VMALLOC reachable.
