From: Mateusz Kulikowski Date: Sun, 31 May 2015 18:19:21 +0000 (+0200) Subject: staging: rtl8192e: Make ethernet addresses properly aligned X-Git-Tag: v4.2-rc1~88^2~417 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=06c111072892d3f5fed9d73d1becb59d3f33410b;p=platform%2Fkernel%2Flinux-exynos.git staging: rtl8192e: Make ethernet addresses properly aligned Reorder ethernet addresses allocated on stack or in non-packed structures to keep them aligned(2). Use ETH_ALEN as array length in places where it was hardcoded to 6. Alignment verified using pahole where possible and target-tested with BUG_ON() trap in ether_addr_copy.
