From 69b8d7bf834c3fcc598aadcf78a736a871befc17 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 23 Aug 2023 13:54:21 -0500 Subject: [PATCH] platform/x86/amd/pmf: Fix a missing cleanup path [ Upstream commit 4dbd6e61adc7e52dd1c9165f0ccaa90806611e40 ] On systems that support slider notifications but don't otherwise support granular slider the SPS cleanup path doesn't run. This means that loading/unloading/loading leads to failures because the sysfs files don't get setup properly when reloaded. Add the missing cleanup path.
