Subject: [PATCH] staging: rtl871x_mlme.c: use is_zero_ether_addr() instead of memcmp()
Date: Thu, 23 Aug 2012 15:20:54 +0800 [thread overview]
Message-ID: <CAPgLHd-SdeouStUf=2C-cmtn-UC-ckt7CUBfUNZBCHm-vB6=TQ@mail.gmail.com> (raw)
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
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.
