From 245a396a9b1a67ac5c3228737c261b3e48708a2a Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 23 Sep 2017 08:06:18 +0200 Subject: [PATCH] iio: adc: twl4030: Fix an error handling path in 'twl4030_madc_probe()' If 'devm_regulator_get()' fails, we should go through the existing error handling path instead of returning directly, as done is all the other error handling paths in this function.
