Bart Van Assche bbb427e342 blkcg: Unlock blkcg_pol_mutex only once when cpd == NULL ... Unlocking a mutex twice is wrong. Hence modify blkcg_policy_register() such that blkcg_pol_mutex is unlocked once if cpd == NULL. This patch avoids that smatch reports the following error: block/blk-cgroup.c:1378: blkcg_policy_register() error: double unlock 'mutex:&blkcg_pol_mutex' Fixes: 06b285bd11 ("blkcg: fix blkcg_policy_data allocation bug") Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Tejun Heo <tj@kernel.org> Cc: <stable@vger.kernel.org> # v4.2+ Signed-off-by: Tejun Heo <tj@kernel.org>		2016-09-30 10:31:20 +02:00
