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" * tag 'usb-4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (42 commits) usb: musb: tusb6010_omap: Do not reset the other direction's packet size usb: musb: Fix trying to suspend while active for OTG configurations usb: host: xhci-plat: propagate return value of platform_get_irq() xhci: Fix command ring stop regression in 4.11 xhci: remove GFP_DMA flag from allocation USB: xhci: fix lock-inversion problem usb: host: xhci-ring: don't need to clear interrupt pending for MSI enabled hcd usb: host: xhci-mem: allocate zeroed Scratchpad Buffer xhci: apply PME_STUCK_QUIRK and MISSING_CAS quirk for Denverton usb: xhci: trace URB before giving it back instead of after USB: serial: qcserial: add more Lenovo EM74xx device IDs USB: host: xhci: use max-port define USB: hub: fix SS max number of ports USB: hub: fix non-SS hub-descriptor handling USB: hub: fix SS hub-descriptor handling USB: usbip: fix nonconforming hub descriptor USB: gadget: dummy_hcd: fix hub-descriptor removable fields doc-rst: fixed kernel-doc directives in usb/typec.rst USB: core: of: document reference taken by companion helper USB: ehci-platform: fix companion-device leak ...
