NACK.

HAVE_VIDEO_BUF_DVB is not "unused" ... This symbol is tested for in the
following locations:

cx88.h:34:#ifdef HAVE_VIDEO_BUF_DVB
cx88.h:327:#ifdef HAVE_VIDEO_BUF_DVB
cx88.h:503:#ifdef HAVE_VIDEO_BUF_DVB
cx88-i2c.c:157:#ifdef HAVE_VIDEO_BUF_DVB
saa7134.h:51:#ifdef HAVE_VIDEO_BUF_DVB
saa7134.h:569:#ifdef HAVE_VIDEO_BUF_DVB

...We need this in order to allow compilation of the cx88 / saa7134 modules
without DVB support. (analog only)

If you want to convert the HAVE_VIDEO_BUF_DVB to a kconfig #ifdef test
for CONFIG_VIDEO_BUF_DVB, that would be acceptable.

Michael Krufky
