X-Git-Tag: firefly_0821_release~176^2~3573^2~1744
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=43aea90116c4fd80fd3d77b268b4a52ad8bf7bfb;p=firefly-linux-kernel-4.4.55.git

[media] pvrusb2: drop g/s_register ioctls

Register access to subdevices no longer needs bridge support for those
ioctls. The v4l2 core handles that these days.
