WARNING at net/wireless/reg.c when wireless network is disconnected

[Thomas Bächler]

Hello,

this warning has been around ever since I switched to 2.6.34, has
accompanied me through the 2.6.35-rc* phase and is still there with
2.6.35. I didn't bother to report it so far, as there seems to be no harm.

Whenever I disconnect/get disconnected from the wireless, I receive the
below warning:
