This has never been used since the driver was merged, but it now causes
a W=1 warning in recent clang versions

drivers/net/wireless/ath/ath9k/main.c:1566:21: error: parameter 'changed_flags' set but not used [-Werror,-Wunused-but-set-parameter]

Remove the bit manipulation on the otherwise unused parameter.

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.
