This is a good change but I think the commit message needs changing.
It's not really certain wireless drivers that is the issue, it's that
linux 4.15 added support to load regulatory.db directly without using
crda.  If the kernel can't load regulatory.db directly it will still
try and use crda.  So this change should allow you to stop using crda
for kernels after 4.15

Thanks

Martin
