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 Signed-off-by: Mikhail Zolotaryov <lebon@lebon.org.ua> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S.
