Subject[PATCH] Staging: rtl8192u: use is_zero_ether_addr() instead of memcmp()
From
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.
