Merge tag 'usb-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman: "Here's the big USB patch set for the 3.6-rc1 merge window. Lots of little changes in here, primarily for gadget controllers and drivers. There's some scsi changes that I think also went in through the scsi tree, but they merge just fine. All of these patches have been in the linux-next tree for a while now.

215Description:
216 USB 3.0 devices may optionally support Latency Tolerance
217 Messaging (LTM). They indicate their support by setting a bit
218 in the bmAttributes field of their SuperSpeed BOS descriptors.
219 If that bit is set for the device, ltm_capable will read "yes".
220 If the device doesn't support LTM, the file will read "no".
221 The file will be present for all speeds of USB devices, and will
222 always read "no" for USB 1.1 and USB 2.0 devices.
