     You didn't actually seem to heed my words about error message.

Well yes I did, but only in the check for platform_get_resource(). As
the comment says - we pass on if that memory region is not given, but if
it is given, it also has to be valid.

    Yes, but what I told you was devm_ioremap_resource() prints the error 
messages itself, so that you don't have to. And you even consented with that. :-)

And don't  you want to do:

	res = PTR_ERR(priv->gmii_sel_reg);

     Well, I've messed with the variable name: 'res' is struct resource *', 
what I meant was *int* variable.

Erm, of course. Sorry for that.
