Subject: [Intel-gfx] [PATCH] drm/i915: Disable RPM wakeref assertions during driver shutdown
Date: Mon,  4 Jan 2021 20:39:05 +0000	[thread overview]
Message-ID: <20210104203905.19248-1-chris@chris-wilson.co.uk> (raw)

As with the regular suspend paths, also disable the wakeref assertions
as we disable the driver during shutdown.

Reported-by: Hans de Goede <hdegoede@redhat.com>
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/2899
Fixes: fe0f1e3bfdfe ("drm/i915: Shut down displays gracefully on reboot")
