Sorry, apparently we have two threads.

Great, thank you for looking into this. Let me know if you have a patch
which you want me to test on a RTL8723BS adapter.

Could you test this instead?

I don't have that much sympathy for a staging driver that's clearly
doing things differently than it was intended (the documentation states
that the function should be called only before wiphy_register(), not
during ndo_open). :-)

I completely understand and I already was worried that this might be
a staging-driver issue, which is why I mentioned this was with a
staging driver in the more detailed bug-report email.

But OTOH, that fix to the driver is simple and looks correct to me since
it only ever has a static regdomain, and the notifier does the work of
applying it to the channels as well.

So I've given your fix a quick try and it leads to a NULL pointer deref.

But now that you've given me a lead on how to fix this (network/wifi
drivers are not really me expertise) I can take a shot at seeing if I
can fix the NULL pointer deref. I Hope to get back to you on that later
today.

Regards,

Hans
