I guess you'd prefer Pekon's ack than mine, but anyway:

Acked-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>

I'd like to point out this driver has other "mis-behaviors" in returning codes
in some other places.

In particular, this pattern can be found repeatedly:

	if (do_something()) {
		err = -ENXIO;
		goto some_other_place;
	}

Which should probably be:

	err = do_something();
	if (err)
		goto some_other_place;

Wei: maybe you'd like to prepare some more patches?
