I'm wondering if the ath12k change should be separated into its own 
patch because 1) it is the most current driver with a dedicated list, 
and 2) it actually doesn't generate a warning because changed_flags is 
used, just not in a meaningful way. But I'll let Kalle make the call on 
that when he returns from holiday.
