Subject: arc_emac: drop redundant mac address check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=99470819b1a89f77c1eb44f6b3328c1aeb2c87d0;p=linux-beck.git

arc_emac: drop redundant mac address check

Checking if MAC address is valid using is_valid_ether_addr() is already done in
of_get_mac_address(). While at it, reorganize checking so it matches checks in
other drivers.
