yep, it's the same as mine, but I thought, that MDIOBUS_UNREGISTERED is not
correct name for this state :) Anyway, thank you for suggestion
It's not actually the same.  The state has to be set before the
device_register() or there is still a leak.
Ah, I see... I forgot to handle possible device_register() error. Will 
send v2 soon, thank you
