Subject: [cfg80211 / iwlwifi] setting wireless regulatory domain doesn't work.

Hi,

I'm trying to change the regulatory domain for my wireless adapter:
Intel Corporation Centrino Advanced-N 6235

But it fails to change from "world" to anything else (say "US")

I enabled debug options used iwlwifi.debug=0x00043FFF for boot and added some printk's which i think should be triggered .. but they are not.
It seems in function "reg_process_pending_hints" the processing is deferred,
but from the code i don't see how it would ever be triggered to complete ?

Hope some can give some hints to what could be going on ...

Attached:
- full syslog from boot till "iw set reg US", which is done at "Oct 18 21:26:09"
- patch.diff with the added debug printk's against 3.12-rc5 (it also contains the patch that was needed to suppress another warning in the iwlwifi driver.
