Subject: 2.6.32-rc3+: bluetooth needs lockdep anotation?

Hi!

I just got this in my dmesg:

							Pavel


drivers/usb/core/inode.c: creating file '005'
hub 5-0:1.0: state 7 ports 2 chg 0000 evt 0002
hub 1-0:1.0: hub_suspend
usb usb1: bus auto-suspend
ehci_hcd 0000:00:1d.7: suspend root hub
uhci_hcd 0000:00:1d.3: reserve dev 5 ep81-INT, period 1, phase 0, 23 us
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
