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?
