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.
