Subject: [PATCH 1/3] sh_eth: Remove redundant alignment adjustment
Date: Thu, 13 Nov 2014 07:04:59 +0000 [thread overview]
Message-ID: <1415862301-28032-2-git-send-email-ykaneko0929@gmail.com> (raw)
In-Reply-To: <1415862301-28032-1-git-send-email-ykaneko0929@gmail.com>
From: Mitsuhiro Kimura <mitsuhiro.kimura.kc@renesas.com>
PTR_ALIGN macro after skb_reserve is redundant, because skb_reserve
function adjusts the alignment of skb->data.
