Subject: [PATCH 0/8 v7] fix gmbus writes and related issues

This patchset addresses a couple of issues with the i915 gmbus
implementation.

v7 adds a final patch to switch to using DRM_ERROR for reporting timeouts.

Daniel Kurtz (8):
  drm/i915/intel_i2c: handle zero-length writes
  drm/i915/intel_i2c: use double-buffered writes
  drm/i915/intel_i2c: always wait for IDLE before clearing NAK
  drm/i915/intel_i2c: use WAIT cycle, not STOP
  drm/i915/intel_i2c: use INDEX cycles for i2c read transactions
  drm/i915/intel_i2c: reuse GMBUS2 value read in polling loop
  drm/i915/intel_i2c: remove POSTING_READ() from gmbus transfers
  drm/i915/intel_i2c: use DRM_ERROR on timeouts
