[Intel-gfx] [PATCH 0/3] drm/i915: atomic_cdclk_freq fixes

[ville.syrjala at linux.intel.com]

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

My little fix for populating intel_state->cdclk with
dev_priv->atomic_cdclk_freq became a little meatier after I realized
that we really need to protect it with what is essentially a crtc
rwlock. That is, writers need to hold all the crtc locks, whereas
readers need to hold at least one.

Ville Syrjälä (3):
  drm/i915: Fix cdclk vs. dev_cdclk mess when not recomputing things
  drm/i915: Protect dev_priv->atomic_cdclk_freq with all the crtc locks
  drm/i915: Simplify error handling in intel_modeset_all_pipes()
