It worked perfectly in 4.14.110.
The next version I have to test is 4.18.20 where I first noticed
problems with loading regulatory.db, but the driver still worked. The
same for 4.19.33, 4.20.17, and 5.0.6:
# journalctl -b | egrep "cfg80211|regulatory|firmware"
May 01 09:38:15 pentiumii-laptop kernel: platform regulatory.0: Direct
firmware load for regulatory.db failed with error -2

It looks like the problems arose in the 5.1-rc series. Here is 5.1-rc7
