Subject: [PATCH v3 03/13] drm/msm: drop drm_gem_object_put_locked()
Date: Tue, 27 Jul 2021 10:11:19 -0700	[thread overview]
Message-ID: <20210727171143.2549475-4-robdclark@gmail.com> (raw)
In-Reply-To: <20210727171143.2549475-1-robdclark@gmail.com>

From: Rob Clark <robdclark@chromium.org>

No idea why we were still using this.  It certainly hasn't been needed
for some time.  So drop the pointless twin codepaths.
