Subject: V4L/DVB (10110): v4l2-ioctl: Fix warnings when using .unlocked_ioctl = __video_ioctl2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=92ab7886119da6375a983713eedab444e32094f6;p=linux-beck.git

V4L/DVB (10110): v4l2-ioctl: Fix warnings when using .unlocked_ioctl = __video_ioctl2

This patch fixes this warning:

drivers/media/video/gspca/gspca.c:1811: warning: initialization from incompatible pointer type

The reason is that the returned argument should be a long, not an
integer.
