[PATCH net-next] drivers/net: Convert uses of compare_ether_addr toether_addr_equal
From: Joe Perches
Date: Sun Sep 01 2013 - 15:21:42 EST
Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.
Done via cocci script: (and a little typing)
$ cat compare_ether_addr.cocci
