[ 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.
