From 64ec7be81097f2c02ecffadbb2eef22ccf4c7e7b Mon Sep 17 00:00:00 2001 From: Mike Westerhof Date: Wed, 16 Apr 2008 20:51:17 +0100 Subject: [PATCH] gta01-fix-jbt-platform-missing-members.patch Created an attachment (id=594) / BZ#79 Add missing platform_data that caused the GTA01 to crash on suspend/resume The interface to the jbt6k74 driver changed slightly; this patch adds the missing platform_data for the GTA01. This prevents a crash while suspending. This patch also makes some minor changes to cleanup and clarify some debug messages.
