Input: wm97xx-core - add retries to wm97xx_read_aux_adc
Add logic to wm97xx_read_aux_adc() to retry reading the adc if the sample failed. This could occur if the previous sample was still in the return register or the sample timed-out. Also avoid a pathologic failure mode by disabling the digitizer and returning -EBUSY after 5 retries.
