Subject: Re: [PATCH 15/31] clk: mediatek: Implement mtk_clk_unregister_fixed_clks() API
Date: Wed, 26 Jan 2022 14:55:32 +0800 [thread overview]
Message-ID: <20220126065532.22463-1-miles.chen@mediatek.com> (raw)
In-Reply-To: <20220122091731.283592-16-wenst@chromium.org>
> mtk_clk_register_fixed_clks(), as the name suggests, is used to register
> a given list of fixed rate clks. However it is lacking a counterpart
> unregister API.
>
> Implement said unregister API so that the various clock platform drivers
> can utilize it to do proper unregistration, cleanup and removal.
>
> In the header file, the register function's declaration is also
> reformatted to fit code style guidelines.
>
> Signed-off-by: Chen-Yu Tsai <wenst@chromium.org>
