Subject: V4L/DVB (6810): media: video: usbvision: add mutex_unlock() to error paths
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0991112c1c4625323df8a582de1b2f8609922248;p=linux-beck.git

V4L/DVB (6810): media: video: usbvision: add mutex_unlock() to error paths

There are a few error paths which don't unlock the usbvision->lock.

So I've added mutex_unlock() calls to fix those paths.
