ASoC: wm_adsp: Return whether changed when writing controls
Functions that update cs_dsp controls need to handle return codes that
indicate whether the control value changed. A return code of 1 indicates
a change, 0 indicates no-change and a negative value is an error
condition.
Acked controls implicitly change value when written so a successful
write shall always report that the value changed.
