From e49068478916ea599765112c3cf3e31c520bce5c Mon Sep 17 00:00:00 2001 From: Santosh Nayak Date: Sat, 23 Jun 2012 07:59:54 -0300 Subject: media: dvb-core: Release semaphore on error path dvb_register_device() commit 82163edcdfa4eb3d74516cc8e9f38dd3d039b67d upstream. There is a missing "up_write()" here. Semaphore should be released before returning error value.
