2017-08-20net: ibm: emac: Fix some error handling path in 'emac_probe()'Christophe Jaillet2-9/+4
If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is known to be 0 at this point. So return -ENODEV instead in the first case and use 'of_iomap()' instead of the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd case. Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes redundant and is removed. While at it, turn a 'err != 0' test into an equivalent 'err' to be more consistent.
