From: Ville Syrjälä <ville.syrjala@linux.intel.com>

While I was frobbing around with DP++ dongles I noticed that out
GMBUS bit-banging fallbacks weren't working as I was expecting, so
after a bit of digging around I came up wit these patches.

Ville Syrjälä (4):
drm/i915: Actually retry with bit-banging after GMBUS timeout
drm/i915: Protect force_bit with gmbus_mutex
drm/i915: Restore GMBUS operation after a failed bit-banging fallback
drm/i915: Make GMBUS timeout message DRM_DEBUG_KMS
