Subject: media: au0828: add VIDEO_V4L2 dependency
Author:  Arnd Bergmann <>
Date:    Thu Jan 4 05:31:32 2018 -0500

After the move of videobuf2 into the common directory, selecting the
au0828 driver with CONFIG_V4L2 disabled started causing a link failure,
as we now attempt to build videobuf2 but it still requires v4l2:

ERROR: "v4l2_event_pending" [drivers/media/common/videobuf/videobuf2-v4l2.ko] 
ERROR: "v4l2_fh_release" [drivers/media/common/videobuf/videobuf2-v4l2.ko] 
ERROR: "video_devdata" [drivers/media/common/videobuf/videobuf2-v4l2.ko] 
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!

This adds the same dependency in au0828 that the other users of videobuf2

Fixes: 03fbdb2fc2b8 ("media: move videobuf2 to drivers/media/common")
Fixes: 05439b1a3693 ("[media] media: au0828 - convert to use videobuf2")
