Merge tag 'usb-4.0-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are some small USB fixes and new device ids for 4.0-rc6. Nothing major, some xhci fixes for reported problems, and some usb-serial device ids. All have been in linux-next for a while" * tag 'usb-4.0-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: USB: ftdi_sio: Use jtag quirk for SNAP Connect E10 usb: isp1760: fix spin unlock in the error path of isp1760_udc_start usb: xhci: apply XHCI_AVOID_BEI quirk to all Intel xHCI controllers usb: xhci: handle Config Error Change (CEC) in xhci driver USB: keyspan_pda: add new device id USB: ftdi_sio: Added custom PID for Synapse Wireless product
