      drm/exynos: Fix NULL pointer exception when suspending without components · d50a1907
      Krzysztof Kozlowski 提交于
      Fix a NULL pointer exception when main exynos drm driver was probed
      successfully but no components were added (e.g. by incomplete DTS). In
      such case the exynos_drm_load() is never called and drvdata is NULL.
      
      The NULL pointer exception may theoretically also happen as a effect of race between
      adding components and main driver: if suspend of the driver happens
      before adding components.

      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.

      - fbc improvements when stolen memory is tight (Ben)
      - cdclk handling improvements for vlv/chv (Ville)
      - proper fix for stuck primary planes on gmch platforms with cxsr (Imre&Ebgert
        Eich)
      - gen8 hw semaphore support (Ben)
      - more execlist prep work from Oscar Mateo
      - locking fixes for primary planes (Matt Roper)
      - code rework to support runtime pm for dpms on hsw/bdw (Paulo, Imre & me), but
        not yet enabled because some fixes from Paulo haven't made the cut
      - more gpu boost tuning from Chris
      - as usual piles of little things all over
