Subject: [media] videodev2.h: add __user to v4l2_ext_control pointers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eadf9e26fab7f9841adcc36f3559dbce7604fcd5;p=linux-beck.git

[media] videodev2.h: add __user to v4l2_ext_control pointers

These are not copied to kernel space by video_usercopy, so mark them
as __user.
