Subject: [PATCH v2 1/2] arch/blackfin: don't generate random mac in bfin_get_ether_addr()
Changed bfin_get_ether_addr() to return a state and to
set no random mac address if the board don't provide one.
Let the caller of bfin_get_ether_addr() set a random mac
address if the return value is not 0.
v2: don't set random mac in bfin_get_ether_addr()
