      drm/i915: be more careful when returning -ENXIO in gmbus transfer · 65e81866
      Daniel Vetter authored
      ... flaky ddc hardware can cause a spurious NAK, resulting in the i2c
      core and drm edid functions not trying to retry the edid transfer.
      
      Luckily the gmbus quiescenting also times out for these cases, so we
      can get out of this mess by returning -ETIMEDOUT for this specific
      case. This way we keep the fast-fail of returning -ENXIO if there is
      no device present, speeding up the boot process.
      
      This regression has been introduced in

          drm/i915/intel_i2c: always wait for IDLE before clearing NAK
      
      v2: Return -ETIMEDOUT for this case and keep the -ENXIO for real NAKs,
      suggested by Daniel Kurtz.

      The last pull I'd like to squeeze into 3.5, safe for the hsw stuff mostly
      bugfixes:
      - last few patches for basic hsw enabling (Eugeni, infoframe support by
       Paulo)
      - Fix up infoframe support, we've hopefully squashed all the cargo-culting
       in there (Paulo). Among all the issues, this finally fixes some of the
       infoframe regressions seen on g4x and snb systems.
      - Fixup sdvo infoframe support, this fixes a regression from 2.6.37.
      - Correctly enable semaphores on snb, we've enabled it already for 3.5,
       but the dmar check was slightly wrong.
      - gen6 irq fixlets from Chris.
      - disable gmbus on i830, the hw seems to be simply broken.
      - fix up the pch pll fallout (Chris & me).
      - for_each_ring macro from Chris - I've figured I'll merge this now to
       avoid backport pain.
      - complain when the rps state isn't what we expect (Chris). Note that this
       is shockingly easy to hit and hence pretty much will cause a regression
       report. But it only tells us that the gpu turbo state got out of whack,
       a problem we know off since a long time (it cause the gpu to get stuck a
       a fixed frequency, usually the lowest one). Chris is working on a fix,
       but we haven't yet found a magic formula that works perfectly (only
       patches that massively reduce the frequency of this happening).
      - MAINTAINERS patch, I'm now officially the guy to beat up."
