Subject: [PATCH] drm/vc4: Mark the device as active when enabling runtime PM.
Date: Mon, 15 May 2017 10:16:15 -0700	[thread overview]
Message-ID: <20170515171615.10168-1-eric@anholt.net> (raw)

Failing to do so meant that we got a resume() callback on first use of
the device, so we would leak the bin BO that we allocated during
probe.

Signed-off-by: Eric Anholt <eric@anholt.net>
Fixes: 553c942f8b2c ("drm/vc4: Allow using more than 256MB of CMA memory.")
