This patchset addresses a couple of issues with the i915 gmbus implementation. v6 is a rebased and trimmed version of the patchset, since the first few patches have already been merged onto drm-intel-next-queued. * Cleans up INDEX cycle implementation * Only remove POSTING_READ() when it immediately precedes another I915_READ().
