   4 Subject: [PATCH] gta01-fix-jbt-platform-missing-members.patch
   5
   6 Created an attachment (id=594) / BZ#79
   7 Add missing platform_data that caused the GTA01 to crash on suspend/resume
   8
   9 The interface to the jbt6k74 driver changed slightly; this patch adds the
  10 missing platform_data for the GTA01.  This prevents a crash while suspending.
  11 This patch also makes some minor changes to cleanup and clarify some debug
  12 messages.
