commit e5cae659597811f8bacc4abc70135dffb48711d5
Author: Michał Winiarski <michal.winiarski@intel.com>
Date:   Sat Jul 14 18:37:03 2018 +0100

    drm/i915/guc: Disable rpm wakeref asserts in GuC irq handler
    
    We're seeing "RPM wakelock ref not held during HW access" warning
    otherwise. Since IRQs are synced for runtime suspend we can just disable
    the wakeref asserts.

This did not seem like it was necessary as it was fixed in drmtip_84. Sorry for being slow at closing bugs during my vacation :p
