This is Acer Aspire V13 laptop and the device in question looks like
below. Any ideas?
I did not yet bisect this but I can do that if needed. Probably has
something to do with commit a01ab81b09c55025365c1de1345b941a18e05529
("ath9k: define correct GPIO numbers and bits mask") and related.
Thanks.

Should be fixed by this:
ath9k: fix GPIO mask for AR9462 and AR9565
https://git.kernel.org/cgit/linux/kernel/git/kvalo/wireless-drivers.git/commit/?id=e024111f6946f45cf1559a8c6fd48d2d0f696d07
Please let me know if it doesn't.
