Merge tag 'drm-intel-fixes-2013-09-26' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

Browse source 
Just a few fixes for regressions and other serious stuff.

Two fix state tracking mismatches, together with an additional patch that
I've submitted to stable (somehow forgotten to tag it) we should have them
fixed now (I hope).

* tag 'drm-intel-fixes-2013-09-26' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: Fix up usage of SHRINK_STOP
  drm/i915: preserve pipe A quirk in i9xx_set_pipeconf
  drm/i915/tv: clear adjusted_mode.flags
  drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER
  drm/i915: Use a temporary va_list for two-pass string handling
