Merge tag 'usb-for-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

usb: patches for v4.1 merge window
As usual, a big pile of commits. This time a total
of 111 non-merge commits.
Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.
The printer gadget has been converted to configfs interface
and the atmel udc has learned suspend/resume with wakeup.
