This is of course harmless, but those devices won't actually work
without this fix:

 93725149794d ("net: qmi_wwan: MDM9x30 specific power management")


And I'm not sure that one is appropriate for stable?  I did consider it
more of a feature than a bugfix myself.  But that's up to you to decide
of course.
