Subject: V4L/DVB (9906): v4l2-compat: test for unlocked_ioctl as well.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3ca81a55256f38d9a8a4d5e9a6a9288ddc672e19;p=linux-beck.git

V4L/DVB (9906): v4l2-compat: test for unlocked_ioctl as well.

The v4l_compat_ioctl32() function only tested for the presence of the
ioctl op, not for unlocked_ioctl. So it would always return an error
when used with drivers that use unlocked_ioctl instead of ioctl.
