Subject[PATCH] staging: rtl8187se: use is_broadcast_ether_addr() instead of memcmp()
From
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

Using is_broadcast_ether_addr() instead of directly use
memcmp() to determine if the ethernet address is broadcast
address.

spatch with a semantic match is used to found this problem.
