Subject: [PATCH v2] staging: r8712u: rtl871x_mlme.c: use is_zero_ether_addr()
 instead of memcmp()

From: Wei Yongjun <yongjun_wei@...ndmicro.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.
