spurious cbb0: bad Vcc request.

[Gregory Steuck <greg@y2004.nest.cx>]

Hello,

I am running i386-current on Dell Lattitude CPt. I see apparently
harmless messages in dmesg (attached) saying:

cbb0: bad Vcc request. sock_ctrl 0x0, sock_status 0x30000710

Is this faulty hardware or just excessively talkative driver?

Thanks
Greg
