Subject: [PATCH 6/8] Blackfin RTC Driver: wait for the write complete interrupt complete before sleeping
Date: Sun, 27 Jul 2008 14:38:25 +0800	[thread overview]
Message-ID: <1217140707-21263-7-git-send-email-cooloney@kernel.org> (raw)
In-Reply-To: <1217140707-21263-1-git-send-email-cooloney@kernel.org>

From: Mike Frysinger <vapier.adi@gmail.com>

Since we use the write complete interrupt, wait for it
to complete before sleeping so we don't wake right back up due to it
