Merge branch 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
* 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (260 commits) usb: renesas_usbhs: fixup inconsistent return from usbhs_pkt_push() usb/isp1760: Allow to optionally trigger low-level chip reset via GPIOLIB. USB: gadget: midi: memory leak in f_midi_bind_config() USB: gadget: midi: fix range check in f_midi_out_open() QE/FHCI: fixed the CONTROL bug usb: renesas_usbhs: tidyup for smatch warnings USB: Fix USB Kconfig dependency problem on 85xx/QoirQ platforms EHCI: workaround for MosChip controller bug usb: gadget: file_storage: fix race on unloading USB: ftdi_sio.c: Use ftdi async_icount structure for TIOCMIWAIT, as in other drivers USB: ftdi_sio.c:Fill MSR fields of the ftdi async_icount structure USB: ftdi_sio.c: Fill LSR fields of the ftdi async_icount structure USB: ftdi_sio.c:Fill TX field of the ftdi async_icount structure USB: ftdi_sio.c: Fill the RX field of the ftdi async_icount structure USB: ftdi_sio.c: Basic icount infrastructure for ftdi_sio usb/isp1760: Let OF bindings depend on general CONFIG_OF instead of PPC_OF . USB: ftdi_sio: Support TI/Luminary Micro Stellaris BD-ICDI Board USB: Fix runtime wakeup on OHCI xHCI/USB: Make xHCI driver have a BOS descriptor. usb: gadget: add new usb gadget for ACM and mass storage ...
