Subject[PATCH] iio: adc128s052: Fix the error handling path of 'adc128_probe()'
Date
A successful 'regulator_enable()' call should be balanced by a
corresponding 'regulator_disable()' call in the error handling path of the
probe, as already done in the remove function.

Update the error handling path accordingly.

Fixes: 913b86468674 ("iio: adc: Add TI ADC128S052")
