When the manager is already at D0, pm_request_resume() is a no-op and amd_resume_runtime() is never called, so the dropped ATTACHED event cannot be recovered and jack detection stops working. Remove the early return: call amd_sdw_process_wake_event() inside a conditional block and fall through to the normal slave-status processing path. Mask AMD_SDW_WAKE_STAT_MASK out of the local status_change_8to11 copy after handling the wake event so the remaining interrupt bits are processed without re-entering the wake path.
