From 42af657feb3481b1dfc130619b5e0d56abc4e0fc Mon Sep 17 00:00:00 2001 From: Li Fei Date: Thu, 28 Feb 2013 15:51:32 +0800 Subject: [PATCH] wl1251: call pm_runtime_put_sync in pm_runtime_get_sync failed case Even in failed case of pm_runtime_get_sync, the usage_count is incremented. In order to keep the usage_count with correct value and runtime power management to behave correctly, call pm_runtime_put(_sync) in such case.
