[PATCH 0/3] iio: adc: twl4030: Fix some error handling issues in 'twl4030_madc_probe()'

From: Christophe JAILLET
Date: Sat Sep 23 2017 - 02:06:03 EST

These 3 patches are all related to error hangling in 'twl4030_madc_probe()'.
They are also all related to commit 7cc97d77ee8a
("iio: adc: twl4030: Fix ADC[3:6] readings")

The semantic of the patches behing slighly different:
- direct return instead of going through the error handling path
- missing function in the error handling path
- spurious pattern (IMO) if unable to enable a regulator
I have splitted them in 3 parts.

Christophe JAILLET (3):
iio: adc: twl4030: Fix an error handling path in
iio: adc: twl4030: Disable the vusb3v1 rugulator in the error handling
path of 'twl4030_madc_probe()'
iio: adc: twl4030: Return an error if we can not enable the vusb3v1
regulator in 'twl4030_madc_probe()'
