Merge tag 'usb-for-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes: usb: patches for v4.9 merge window This time around we have 92 non-merge commits. Most of the changes are in drivers/usb/gadget (40.3%) with drivers/usb/gadget/function being the most active directory (27.2%). As for UDC drivers, only dwc3 (26.5%) and dwc2 (12.7%) have really been active. The most important changes for dwc3 are better support for scatterlist and, again, throughput improvements. While on dwc2 got some minor stability fixes related to soft reset and FIFO usage. Felipe Tonello has done some good work fixing up our f_midi gadget and Tal Shorer has implemented a nice API change for our ULPI bus. Apart from these, we have our usual set of non-critical fixes, spelling fixes, build warning fixes, etc.
