Subject: V4L/DVB (5249): Fix compiler warning in vivi.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4acf26703e6cabceb6838ee9c4f75f765ad96915;p=linux-beck.git

V4L/DVB (5249): Fix compiler warning in vivi.c

The result of copy_to_user was not used, so the compiler complained
now a warning will be issued if copy_to_user fails.
