Subject: [PATCH 12/14] ARM: suspend: mach-exynos4: cleanup s3c_cpu_save
Date: Mon, 13 Jun 2011 18:18:54 +0100 [thread overview]
Message-ID: <E1QWAms-0002ea-5n@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20110613171446.GF13643@n2100.arm.linux.org.uk>
s3c_cpu_save does not need to save any registers with the new
cpu_suspend calling convention. Remove these redundant instructions.
