Subject: [PATCH v2 5/7] clk: mediatek: mt6797: use mtk_clk_simple_probe to simplify driver
Date: Tue, 24 May 2022 16:38:38 +0800	[thread overview]
Message-ID: <20220524083843.9994-6-miles.chen@mediatek.com> (raw)
In-Reply-To: <20220524083843.9994-1-miles.chen@mediatek.com>

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.
