Merge tag 'usb-for-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes: usb: changes for v4.12 With 51 non-merge commits, this is one of the smallest USB Gadget pull requests. Apart from your expected set of non-critical fixes, and other miscellaneous items, we have most of the changes in dwc3 (52.5%) with all other UDCs following with 34.8%. As for the actual changes, the most important of them are all the recent changes to reduce memory footprint of dwc3, bare minimum dual-role support on dwc3 and reworked endpoint count and initialization routines.
