That patch (in combination with some others) renamed the config variable

Some code, like saa7134.h, was not updated and is still looking at

There is a script I wrote called check_config_defines.pl that should find
stuff like this, but in this case it misses it.  The kernel source defines
CONFIG_VIDEO_BUF_DVB since it has all the old code in it, so it doesn't appear
to be missing.  I fixed the script so it uses the v4l-dvb Kconfig replace the
corresponding kernel files, as opposed to be combined when them.  Now it finds
the errors:
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/cx23885/cx23885.h:31
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/cx88/cx88-i2c.c:156
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/cx88/cx88.h:34
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/cx88/cx88.h:320
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/cx88/cx88.h:494
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/saa7134/saa7134.h:51
Unknown config CONFIG_VIDEO_BUF_DVB in linux/drivers/media/video/saa7134/saa7134.h:562

I wonder if instead of changing these to CONFIG_VIDEOBUF_DVB, it would be
better to use CONFIG_VIDEO_SAA7134_DVB, CONFIG_VIDEO_CX88_DVB, etc.

One could always have a cx88 card with DVB and a saa7134 card without dvb.
