All the helper functions (i.e. hp_wmi_dock_state, hp_wmi_tablet_state, ...) using hp_wmi_perform_query to perform an HP WMI query shadow the returned value in case of error. We return -EINVAL only when the HP WMI query returns a positive value (the specific error code) to not mix this up with the actual value returned by the helper function.
