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.
