From: Shubhrajyoti D <[email protected]> pm_runtime_get_sync returns a signed integer. In case of errors it returns a negative value. This patch fixes the error check by making it signed instead of unsigned thus preventing register access if get_sync_fails. Also passes the error cause to the debug message.
