Mikhail Zolotaryov 62f0c338d1 powerpc 4xx EMAC driver: device name reported on timeout is not correct
Hi,

IBM EMAC driver performs device reset (drivers/net/ibm_newemac/core.c:
emac_probe() -> emac_init_phy() -> emac_reset()) before registering
appropriate net_device (emac_probe() -> register_netdev()), so
net_device name contains raw format string during EMAC reset ("eth%d").

If the case of reset timeout, emac_report_timeout_error() function is
called to report an error. The problem is this function uses net_device
name to report device related, which is not correct, as a result in the
kernel log buffer we see:

eth%d: reset timeout

The solution is to print device_node full_name instead. After applying
the patch proposed, error string is like the following:

/plb/opb/ethernet@ef600e00: reset timeout
