Subject: regression 3.11-rc1: rmmod hangs after tracing module

Hi Steven,

During testing of our brcmfmac wireless driver I had a trace-cmd running 
along (trace-cmd record -e brcmfmac:*). After the test I stopped the 
trace, unplugged my usb device and did a rmmod resulting in the attached 
lockdep splat. Hope you have an idea what is going wrong here.

Regards,
Arend
