From 929a4d289de9d6bf74b4c7d093ccc4823c9f56e9 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 29 Jun 2022 01:17:38 +0300 Subject: [PATCH] mfd: intel_soc_pmic_bxtwc: Create sysfs attributes using core driver's facility Driver core takes care of sysfs attributes. Use this facility instead of doing it explicitly in ->probe() and ->remove().
