BTW, if the commit that introduced the problem is known, please add a Fixes: tag pointing to it to the patch changelog (I did that for this one). > --- > drivers/acpi/processor_driver.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/drivers/acpi/processor_driver.c b/drivers/acpi/processor_driver.c > index f4e02ae..11154a3 100644 > --- a/drivers/acpi/processor_driver.c > +++ b/drivers/acpi/processor_driver.c > @@ -200,7 +200,8 @@ static int acpi_pss_perf_init(struct acpi_processor *pr, > goto err_remove_sysfs_thermal; > } > > - sysfs_remove_link(&pr->cdev->device.kobj, "device"); > + return 0; > + > err_remove_sysfs_thermal: > sysfs_remove_link(&device->dev.kobj, "thermal_cooling"); > err_thermal_unregister: >

The processor cooling device is no longer present for passive thermal control. The change commit 239708a3af44 ("ACPI: Split out ACPI PSS from ACPI Processor driver") moved the processing to a new function acpi_pss_perf_init, but missing "return 0" after successful creation. This causes the error handling functions to be called, which will delete the previously created processor cooling device.
