FYI, just found this V4L build failure in -rc9:

 drivers/built-in.o: In function `saa7146_unregister_device':
 : undefined reference to `video_unregister_device'
 drivers/built-in.o: In function `saa7146_register_device':
 : undefined reference to `video_device_alloc'
 drivers/built-in.o: In function `saa7146_register_device':
 : undefined reference to `video_device_release'
 [ ... etc ... ]

this is caused by the attached config:

  CONFIG_VIDEO_BUF=m
  CONFIG_VIDEO_BUF_DVB=m

combined with:

  CONFIG_VIDEO_SAA7146=y
  CONFIG_VIDEO_SAA7146_VV=y

so it seems like a drivers/video/Kconfig bug - this combination should 
not be possible.
