From 36e4d8826b317080e283e4edd08bf8d5ac706f38 Mon Sep 17 00:00:00 2001 From: Heba Aamer Date: Fri, 30 Jan 2015 00:11:36 +0200 Subject: [PATCH] staging: rtl8712: fix Prefer ether_addr_copy() over memcpy() This patch fixes the following checkpatch.pl warning: Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2) pahole showed that the struct used pnetdev->dev_addr is aligned to u16. Moreover mac is a simple array, pdata is a pointer that starts from an even offset.
