From f931076d32b686014cf31f12cdb2781aa26bff46 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 21 Aug 2021 12:37:24 +0200 Subject: [PATCH] iio: adc128s052: Fix the error handling path of 'adc128_probe()' commit bbcf40816b547b3c37af49168950491d20d81ce1 upstream. 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.
