Merge tag 'usb-4.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are a handful of USB driver fixes for 4.14-rc5. There is the "usual" usb-serial fixes and device ids, USB gadget fixes, and some more fixes found by the fuzz testing that is happening on the USB layer right now. All of these have been in my tree this week with no reported issues" * tag 'usb-4.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: usb: usbtest: fix NULL pointer dereference usb: gadget: configfs: Fix memory leak of interface directory data usb: gadget: composite: Fix use-after-free in usb_composite_overwrite_options usb: misc: usbtest: Fix overflow in usbtest_do_ioctl() usb: renesas_usbhs: Fix DMAC sequence for receiving zero-length packet USB: dummy-hcd: Fix deadlock caused by disconnect detection usb: phy: tegra: Fix phy suspend for UDC USB: serial: console: fix use-after-free after failed setup USB: serial: console: fix use-after-free on disconnect USB: serial: qcserial: add Dell DW5818, DW5819 USB: serial: cp210x: add support for ELV TFD500 USB: serial: cp210x: fix partnum regression USB: serial: option: add support for TP-Link LTE module USB: serial: ftdi_sio: add id for Cypress WICED dev board
