Warning emited by 2.6.24-rc6-git5

[Chris Clayton <chris2553@googlemail.com>]

Hi,

Please cc me on any reply - I'm not subscribed.

I've just built and installed 2.6.24-rc6-git5 and noticed the following 
warning when I rebooted.

lspci shows my wireless card to be RaLink RT2561/RT61 802.11g PCI. It's a 
Belkin F5D7010. The driver (rt61pci) is built as a module. Despite the 
warning, networking sees to be working OK.

In case it helps, the complete output from dmesg follows (The odd-looking mac 
address for my AP is my alteration)
