    drm - Fix hrtimer, don't reset timer->function to NULL in timeout handler.
    
    * The same hrtimer object is activated multiple times by i915(4), so we
      mustn't clear timer->function in the timeout handler.
    
    * This seems to fix the powersaving issues in i915(4) from the update to
      Linux 4.7.10 code in 8621f4070e7cb342161183c980ae7fce2fd8124e.
