      drm/i915: fix psr match conditions screw ups. · b1972961
      Dave Airlie authored
      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.
