-From 26a1d7115299dcb17a9e9effc780ceba58afa91b Mon Sep 17 00:00:00 2001
-From: Mike Westerhof <mwester@dls.net>
-Date: Sun, 10 Aug 2008 09:13:46 +0100
-Subject: [PATCH] fix-suspend-backlight-timing-gta01.patch
-
- This patch adds the gta01 backlight callback that defers the
- restoring of the backlight until after the jbt driver has
- resumed. This doesn't eliminate the flashing of the LCD on
- the gta01, but it reduces it considerably.
