When request_firmware() finds an already open firmware object it will wait for that object to become fully loaded and then check the status. As __fw_state_wait_common() succeeds the timeout value returned will be truncated in _request_firmware_prepare() and interpreted as -EPERM. Prior to "firmware: do not use fw_lock for fw_state protection" the code did test if we where in the "done" state before sleeping, causing this particular code path to succeed, in some cases. As the callers are interested in the result of the wait and not the remaining timeout the return value of __fw_state_wait_common() is changed to signal "done" or "error", which simplifies the logic in _request_firmware_load() as well.
