3.2.44-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Li Fei <fei.li@xxxxxxxxx> commit c10b90d85a5126d25c89cbaa50dc9fdd1c4d001a upstream. 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_noidle in such case. In __hwspin_lock_request, module_put is also called before return in pm_runtime_get_sync failed case.
