>From recent experience working on
https://bugzilla.kernel.org/show_bug.cgi?id=70881, it appears that the
kernels default is to:

- On module load, default to global region
- When associating to an AP, reset the local region to match the APs

It seems like unless you are going to run in AP mode, or your local
region is more permissive than global, there shouldn't a need override
locally?

Title:
  Incorrect regulatory domain set during boot [BCM43225]

Status in “wireless-regdb” package in Ubuntu:
  New

Bug description:
  During boot my system incorrectly sets the regulatory domain to JP
  when it should be GB. Everything else is set to GB on my system so
  surely my regdom should be too.

  $ dmesg | grep JP

  As you can see there is a significant difference in the settings.

  There is a discussion for Arch Linux here:
  https://bbs.archlinux.org/viewtopic.php?id=124574

  I'm not sure if this is the correct package or not, and I'm not sure
  if this is affected directly by the kernel or not, so I apologise if
  this is incorrect.
