Merge tag 'usb-4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are a number of small USB fixes for 4.12-rc2
Most of them come from Johan, in his valiant quest to fix up all
drivers that could be affected by "malicious" USB devices. There's
also some fixes for more "obscure" drivers to handle some of the
vmalloc stack fallout (which for USB drivers, was always the case, but
very few people actually ran those systems...)
Other than that, the normal set of xhci and gadget and musb driver
fixes as well.
All have been in linux-next with no reported issues"
