"mclk" is retrieved from the configuration and assigned to adau1372->clk. However adau1372->mclk (==NULL) is used for clk_prepare_enable() and clk_disable_unprepare() which don't have any effect.
Remove .clk from struct adau1372 and use .mclk throughout. This change ensures that the input clock is switched on/off when the bias level is changed.
