From 6977a6b01dc14a1a3d6b70cacfc22dc83cf11984 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 23 Aug 2012 14:55:02 +0800 Subject: [PATCH] orinoco: use is_zero_ether_addr() instead of memcmp() Using is_zero_ether_addr() instead of directly use memcmp() to determine if the ethernet address is all zeros. spatch with a semantic match is used to found this problem.
