Subject: [PATCH 1/3] ASoC: ti: omap-mcbsp: Ignore errors for getting fck_src
Date: Wed,  5 Jul 2023 21:03:22 +0200	[thread overview]
Message-ID: <20230705190324.355282-2-andreas@kemnade.info> (raw)
In-Reply-To: <20230705190324.355282-1-andreas@kemnade.info>

Commit 349355ce3a05 ("ARM: OMAP2+: Drop legacy platform data for omap4 mcbsp")
dropped prcm_fck for omap4, so the clk_src might not be available making the
clk_get(src) fail. In such cases, rely on the devicetree to assign
the correct parent.
