4.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Huang Rui <[email protected]> commit bec5f70dad45f7ad63f97aa0988821532ebeade7 upstream. The return value 0 (false) means fail to find GPIO in atomctrl_get_pp_assign_pin. "-1" returns true as bool actually.
