Subject: [PATCH 2/7] clk: mediatek: mt2712: use mtk_clk_simple_probe to simplify driver
Date:   Thu, 22 Sep 2022 17:18:30 +0800
Message-ID: <20220922091841.4099-3-miles.chen@mediatek.com>
In-Reply-To: <20220922091841.4099-1-miles.chen@mediatek.com>

Precedence: bulk

mtk_clk_simple_probe was added by Chun-Jie to simply common flow
of MediaTek clock drivers and ChenYu enhanced the error path of
mtk_clk_simple_probe and added mtk_clk_simple_remove.

Let's use mtk_clk_simple_probe and mtk_clk_simple_probe in other
MediaTek clock drivers as well.
