Subject: [PATCH v2 3/5] drm/mediatek: Change disp/ddp term to mutex in mtk mutex driver
Date:   Thu,  7 Jan 2021 07:17:27 +0800
Message-Id: <20210106231729.17173-4-chunkuang.hu@kernel.org>
In-Reply-To: <20210106231729.17173-1-chunkuang.hu@kernel.org>
References: <20210106231729.17173-1-chunkuang.hu@kernel.org>
Precedence: bulk

From: CK Hu <ck.hu@mediatek.com>

mtk mutex is used by both drm and mdp driver, so change disp/ddp term to
mutex to show that it's a common driver for drm and mdp.
