Subject: [PATCH] drm/i915/selftests: Avoid warning if runtime pm is disabled
Date: Fri,  6 Jul 2018 21:59:47 +0100	[thread overview]
Message-ID: <20180706205947.11209-1-chris@chris-wilson.co.uk> (raw)

Inside the mock GEM device, we try to grab the runtime pm for the fake
device to prevent it from ever suspending. However, if CONFIG_PM is not
set, trying to obtain the wakref returns an error which we WARN about.
Suppress the expected warning.
