Subject: [PATCH 4/4] ARM: S3C64XX: PM: Synchronise wakeup mask on suspend
Date: Thu, 20 May 2010 10:34:55 +0100	[thread overview]
Message-ID: <1274348095-9390-4-git-send-email-ben-linux@fluff.org> (raw)
In-Reply-To: <1274348095-9390-1-git-send-email-ben-linux@fluff.org>

Use the new wakeup mask synchronisation code to set the
relevant wakeup mask bits.
