From 8f2ef2610f9b7920c5ce847042d5a0193bc42bcb Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 23 Aug 2024 22:50:39 -0700 Subject: Input: zforce_ts - switch to using devm_regulator_get_enable() The driver does not actively manage regulator state past probe() time, so we can use devm_regulator_get_enable() to simplify the code.
