Subject[PATCH 3.18 13/86] net: stmmac: move stmmac_check_ether_addr() to driver probe
Date
From: Vinod Koul <vkoul@kernel.org>

[ Upstream commit b561af36b1841088552464cdc3f6371d92f17710 ]

stmmac_check_ether_addr() checks the MAC address and assigns one in
driver open(). In many cases when we create slave netdevice, the dev
addr is inherited from master but the master dev addr maybe NULL at
that time, so move this call to driver probe so that address is
always valid.
