Subject: [PATCH 1/3] drm/msm: dpu: Clear frame_busy_mask bit after trace
Date: Wed, 19 Sep 2018 14:33:48 -0400 [thread overview]
Message-ID: <20180919183426.200909-1-sean@poorly.run> (raw)
From: Sean Paul <seanpaul@chromium.org>
We're printing the frame_busy_mask in a trace, but after it's been
cleared. This, as it turns out, is pretty pointless.
