Subject: media: v4l2-ioctl.c: don't copy back the result for -ENOTTY
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dbcecbbd1d078f0c45dfce5afe4a08e617129a14;p=pandora-kernel.git

media: v4l2-ioctl.c: don't copy back the result for -ENOTTY

commit 181a4a2d5a0a7b43cab08a70710d727e7764ccdd upstream.

If the ioctl returned -ENOTTY, then don't bother copying
back the result as there is no point.
