    drm/radeon/atom: initialize more atom interpretor elements to 0
    
    BugLink: http://bugs.launchpad.net/bugs/1221794
    
    commit 42a21826dc54583cdb79cc8477732e911ac9c376 upstream.
    
    The ProcessAuxChannel table on some rv635 boards assumes
    the divmul members are initialized to 0 otherwise we get
    an invalid fb offset since it has a bad mask set when
    setting the fb base.  While here initialize all the
    atom interpretor elements to 0.

and fixed (& currently queued for 3.8.13.11) with

    drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)
    
    The OUTPUT_ENABLE action jumps past the point in the coder where
    the data_offset is set on certain rs780 cards.  This worked
    previously because the OUTPUT_ENABLE action is always called
    immediately after the ENABLE action so the data_offset remained
    set.  In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57
    (drm/radeon/atom: initialize more atom interpretor elements to 0),
    we explictly reset data_offset to 0 between atom calls which then
    caused this to fail.  The fix is to just skip calling the
    OUTPUT_ENABLE action on the problematic chipsets.  The ENABLE
    action does the same thing and more.  Ultimately, we could
    probably drop the OUTPUT_ENABLE action all together on DCE3
    asics.

Title:
  HDMI not working after update to linux image 3.8.0.31.46

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Operating System: Ubuntu 13.04 64-bit
  Hardware: Acer Aspire x3450 AMD Athlon II X2 220 Processor x 2; Graphics Gallium 0.4 on AMD RS880; Monitor Samsung Syncmaster P2250.
  Problem/Bug: HDMI video output from pc to Samsung Syncmaster P2250 via HDMI/DVI adaptor cable no longer works after Ubuntu's Software Updater updated my system from linux-image 3.8.0.30.44 to 3.8.0.31.46.
  I get an initial purple screen, without the Ubuntu logo, then absolutely nothing.
  Had to revert to old style analogue connection to make my system useable.
