Subject: [PATCH v5 16/28] clk: Change clk_core_init_rate_req prototype
Date: Mon, 16 May 2022 15:25:15 +0200 [thread overview]
Message-ID: <20220516132527.328190-17-maxime@cerno.tech> (raw)
In-Reply-To: <20220516132527.328190-1-maxime@cerno.tech>
The expectation is that a clk_rate_request structure is supposed to be
initialized using clk_core_init_rate_req(), yet the rate we want to
request still needs to be set by hand.
Let's just pass the rate as a function argument so that callers don't
have any extra work to do.
