Subject: [PATCH v5 04/18] clk: qcom: clk-hfpll: use poll_timeout macro
Date: Mon, 21 Mar 2022 16:38:41 +0100 [thread overview]
Message-ID: <20220321153855.12082-5-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20220321153855.12082-1-ansuelsmth@gmail.com>
Use regmap_read_poll_timeout macro instead of do-while structure.
