Subject: [PATCH 03/06] ARM: shmobile: Rework EMEV2 scu_base variable
Date: Wed, 13 Feb 2013 13:46:57 +0000 [thread overview]
Message-ID: <20130213134657.12153.27160.sendpatchset@w520> (raw)
In-Reply-To: <20130213134628.12153.47120.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Rename the static scu_base variable into shmobile_scu_base.
Later in the series the shmobile_scu_base variable will be
made into a global variable so this is preparation only.
