From 30b48e2dbe7f4d78fb8f7abbef9851ec36a93dff Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Fri, 16 Sep 2016 19:54:37 +0530 Subject: [PATCH] Staging: ks7010: Replace memset with eth_zero_addr Use eth_zero_addr to assign zero address to the given address array instead of memset when the second argument in memset is address of zero. Coccinelle was used to do the replacement and add the header file linux/etherdevice.h if not already present.
