commit 1b1fe542b6f010cf6bc7e1c92805e1c0e133e007 upstream.
Now that we've added a 'trigger_async_request' knob to test the request_firmware_nowait() API, let's use it. Also add tests for the empty ("") string, since there have been a couple errors in that handling already.
Since we now have real ways that the sysfs write might fail, let's add the appropriate check on the 'echo' lines too.
