Subject: wl1251: call pm_runtime_put_sync in pm_runtime_get_sync failed case
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=42af657feb3481b1dfc130619b5e0d56abc4e0fc;p=deliverable%2Flinux.git

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.
