      for MST I need to reuse this, so just move it now.

      Dave Airlie 提交于
      DP MST will need connectors that aren't connected to specific
      encoders, add some checks in advance to avoid oopses.

      drm/i915: fix psr match conditions screw ups. · b1972961
      Dave Airlie 提交于
      Not enough brown paper bags, you'll have to share one.
      (oops below).
      
      The initial match condition code was racy (locking is coming I hear).
      
      then along came:
      cd234b0b
      drm/i915: Do not dereference NULL crtc or fb until after checking
      
      Chris made an attempt to fix it, Ben "reviewed" it.
      Daniel merged it.
      
      Then
      drm/i915: Make use of intel_fb_obj() (v2)
      2ff8fde1
      
      made it worse by removing the obj check later.
      
      All in all, my laptop can't barely turn off the display
      without hitting this.
      
      Posted to #intel-gfx out of niceness, but I've merged
      this already into drm-next.
      
      Here's an oops.
