From: Mauro Carvalho Chehab Date: Sun, 13 Apr 2008 18:10:00 +0000 (-0300) Subject: V4L/DVB (7566): videobuf-dvb: allow its usage with videobuf-vmalloc X-Git-Tag: v2.6.26-rc1~1084^2~148 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59d3448995a4c0ca98cbe82f6dac9460323377c1;p=linux-2.6 V4L/DVB (7566): videobuf-dvb: allow its usage with videobuf-vmalloc videobuf-dvb were still using a function that were videobuf-dma-sg dependent. This patch creates a generic handler for this function. This way, videobuf-dvb can now work with all videobuf implementations.
