Merge tag 'usb-for-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes: USB: changes for v4.11 Here's the big pull request for the Gadget API. Again the majority of changes sit in dwc2 driver. Most important changes contain a workaround for GOTGCTL being wrong, a sleep-inside-spinlock fix and the big series of cleanups on dwc2. One important thing on dwc3 is that we don't anymore need gadget drivers to cope with unaligned OUT transfers for us. We have support for appending one extra chained TRB to align transfer ourselves. Apart from these, the usual set of typos, non-critical fixes, etc.
