From 901401166464dc1875825235bb2541af31b4c384 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 22 Jul 2014 23:11:03 +0900 Subject: [PATCH] ALSA: bebob: Fix a missing to unlock mutex in error handling case In error handling case, special_clk_ctl_put() returns without unlock_mutex(), therefore the mutex is still locked. This commit moves mutex_lock() after the error handling case. This commit is my solution for this post.
