iio: adc: twl4030: Disable the vusb3v1 rugulator in the error handling path of 'twl4030_madc_probe()'
Commit7cc97d77ee
has introduced a call to 'regulator_disable()' in the .remove function. So we should also have such a call in the .probe function in case of error after a successful 'regulator_enable()' call. Add a new label for that and use it. Fixes:7cc97d77ee
