Merge tag 'usb-3.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB bugfix from Greg KH:
"Here is a single bugfix that resolves the "can not build the OHCI
driver with CONFIG_PM disabled" problem that lots of people have been
reporting with 3.11-rc7. Sorry about that one, it missed my build
tests, and it seems, a number of others as well.
Thank goodness for Guenter :)"
