[ Upstream commitfaae443738] Currently, acpi_device_remove_notify_handler() may return while the notify handler being removed is still running which may allow the module holding that handler to be torn down prematurely. Address this issue by making acpi_device_remove_notify_handler() wait for the handling of all the ACPI events in progress to complete before returning.
