From 53063846affd27def6f96e13a9fb80b9a3c2d126 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 23 Sep 2017 08:06:20 +0200 Subject: iio: adc: twl4030: Return an error if we can not enable the vusb3v1 regulator in 'twl4030_madc_probe()' If we can not enable the regulator, go through the error handling path instead of silently continuing.
