Merge tag 'usb-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are a bunch of USB fixes for 4.10-rc3. Yeah, it's a lot, an artifact of the holiday break I think. Lots of gadget and the usual XHCI fixups for reported issues (one day that driver will calm down...) Also included are a bunch of usb-serial driver fixes, and for good measure, a number of much-reported MUSB driver issues have finally been resolved. All of these have been in linux-next with no reported issues" * tag 'usb-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (72 commits) USB: fix problems with duplicate endpoint addresses usb: ohci-at91: use descriptor-based gpio APIs correctly usb: storage: unusual_uas: Add JMicron JMS56x to unusual device usb: hub: Move hub_port_disable() to fix warning if PM is disabled usb: musb: blackfin: add bfin_fifo_offset in bfin_ops usb: musb: fix compilation warning on unused function usb: musb: Fix trying to free already-free IRQ 4 usb: musb: dsps: implement clear_ep_rxintr() callback usb: musb: core: add clear_ep_rxintr() to musb_platform_ops USB: serial: ti_usb_3410_5052: fix NULL-deref at open USB: serial: spcp8x5: fix NULL-deref at open USB: serial: quatech2: fix sleep-while-atomic in close USB: serial: pl2303: fix NULL-deref at open USB: serial: oti6858: fix NULL-deref at open USB: serial: omninet: fix NULL-derefs at open and disconnect USB: serial: mos7840: fix misleading interrupt-URB comment USB: serial: mos7840: remove unused write URB USB: serial: mos7840: fix NULL-deref at open USB: serial: mos7720: remove obsolete port initialisation USB: serial: mos7720: fix parallel probe ...
