From 3bce071a301f44ffd08bada9b2e8238b625f8f8c Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 26 Oct 2020 11:53:52 +0100 Subject: [PATCH] hwmon: (pmbus) shrink code and remove pmbus_do_remove() The only action currently performed in pmbus_do_remove() is removing the debugfs hierarchy. We can schedule a devm action at probe time and remove pmbus_do_remove() entirely from all pmbus drivers.
