X-Git-Tag: firefly_0821_release~31016^2~114
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ed10b06d8da204ce5f8d1b5b1a9d4df6565847c9;p=firefly-linux-kernel-4.4.55.git

V4L/DVB (5104): Moved several stuff that were at cx88-video to cx88-blackbird.c

cx88-blackbird were using some ioctl handling that were previously on
cx88-video.
