When removing the ACPI notify/address space handlers, the WMI devices
are still active and might still depend on ACPI EC access or
WMI events.
Fix this by removing the ACPI handlers after all WMI devices
associated with an ACPI device have been removed.
Hello,
i would advise against including this patch in the next stable kernels.
The WMI ACPI notify handler is still using list_for_each_entry() which is
not safe when the WMI devices are removed before the ACPI notify handler.
This issue existed inside the WMI code for a long time, but this patch might
trigger it. Since no users reported any issues regarding ACPI errors during
WMI removal, i would drop this patch.
Ack, I'll drop it.
