From: Cezary Rojewski Date: Wed, 21 Feb 2024 15:25:14 +0000 (+0100) Subject: ASoC: codecs: rt5616: Simplify mclk initialization X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f76de61ad1eb725cc05727377ccd4adda336b822;p=users%2Fjedix%2Flinux-maple.git ASoC: codecs: rt5616: Simplify mclk initialization Most of clk_xxx() functions do check if provided clk-pointer is non-NULL. These do not check if the pointer is an error-pointer. Providing such to a clk_xxx() results in a panic. By utilizing _optional() variant of devm_clk_get() the driver code is both simplified and more robust. There is no need to remember about IS_ERR(clk) checks each time mclk is accessed.
