Subject: [PATCH] ASoC: mxs-saif: Handle errors for clk_enable
Git-commit: 2ecf362d220317debf5da376e0390e9f7a3f7b29
Patch-mainline: v5.18-rc1
References: git-fixes
As the potential failure of the clk_enable(),
it should be better to check it, like mxs_saif_trigger().
Fixes: d0ba4c014934 ("ASoC: mxs-saif: set a base clock rate for EXTMASTER mode work")
