Merge tag 'usb-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman: "Here's the big USB patch set for the 3.6-rc1 merge window. Lots of little changes in here, primarily for gadget controllers and drivers. There's some scsi changes that I think also went in through the scsi tree, but they merge just fine. All of these patches have been in the linux-next tree for a while now. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fix up trivial conflicts in include/scsi/scsi_device.h (same libata conflict that Jeff had already encountered) * tag 'usb-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (207 commits) usb: Add USB_QUIRK_RESET_RESUME for all Logitech UVC webcams usb: Add quirk detection based on interface information usb: s3c-hsotg: Add header file protection macros in s3c-hsotg.h USB: ehci-s5p: Add vbus setup function to the s5p ehci glue layer USB: add USB_VENDOR_AND_INTERFACE_INFO() macro USB: notify phy when root hub port connect change USB: remove 8 bytes of padding from usb_host_interface on 64 bit builds USB: option: add ZTE MF821D USB: sierra: QMI mode MC7710 moved to qcserial USB: qcserial: adding Sierra Wireless devices USB: qcserial: support generic Qualcomm serial ports USB: qcserial: make probe more flexible USB: qcserial: centralize probe exit path USB: qcserial: consolidate usb_set_interface calls USB: ehci-s5p: Add support for device tree USB: ohci-exynos: Add support for device tree USB: ehci-omap: fix compile failure(v1) usb: host: tegra: pass correct pointer in ehci_setup() USB: ehci-fsl: Update ifdef check to work on 64-bit ppc USB: serial: keyspan: Removed unrequired parentheses. ...
