Subject: [PATCH v16 01/20] drm/msm: Remove dangling submitqueue references
Date: Tue,  1 Sep 2020 09:46:18 -0700	[thread overview]
Message-ID: <20200901164707.2645413-2-robdclark@gmail.com> (raw)
In-Reply-To: <20200901164707.2645413-1-robdclark@gmail.com>

From: Rob Clark <robdclark@chromium.org>

Currently it doesn't matter, since we free the ctx immediately.  But
when we start refcnt'ing the ctx, we don't want old dangling list
entries to hang around.
