After applying the full series, mt8195_afe_fe_trigger() still calls the enable helper like this on START/RESUME: mt8195_afe_paired_memif_clk_enable(substream, dai, 1); so a failure from clk_enable() would not be propagated back through the DAI .trigger callback. Patch 6 handles the prepare-side helper in startup(), but I do not see the enable-side helper being handled by any later patch. Should the START/RESUME path check this return value and unwind the trigger state if enabling the paired MEMIF clock fails?
