Fix this by calling a clk_disable_unprepare() on error paths after MCLK has been enabled. v2: Guard clk_disable_unprepare() with SND_SOC_DAPM_EVENT_ON() to avoid callling it in the EVENT_OFF error path where MCLK was never enabled. v3: Restored missing clk_disable_unprepare() guard in patch 2 that was accidentally dropped during v2 rebase.
