-From de64d8449b10dc39eebdee6bc01409cd0197e38a Mon Sep 17 00:00:00 2001
-From: Andy Green <andy@openmoko.com>
-Date: Wed, 2 Jul 2008 22:38:15 +0100
-Subject: [PATCH] add-use-pcf50633-resume-callback-jbt6k74.patch
-
-Adds the resume callback stuff to glamo, then changes
-jbt6k74 to no longer use a sleeping workqueue, but to
-make its resume actions dependent on pcf50633 and
-glamo resume (for backlight and communication to LCM
-respectively)
