Merge branch 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6
* 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6: (172 commits) USB: Add support for SuperSpeed isoc endpoints xhci: Clean up cycle bit math used during stalls. xhci: Fix cycle bit calculation during stall handling. xhci: Update internal dequeue pointers after stalls. USB: Disable auto-suspend for USB 3.0 hubs. USB: Remove bogus USB_PORT_STAT_SUPER_SPEED symbol. xhci: Return canceled URBs immediately when host is halted. xhci: Fixes for suspend/resume of shared HCDs. xhci: Fix re-init on power loss after resume. xhci: Make roothub functions deal with device removal. xhci: Limit roothub ports to 15 USB3 & 31 USB2 ports. xhci: Return a USB 3.0 hub descriptor for USB3 roothub. xhci: Register second xHCI roothub. xhci: Change xhci_find_slot_id_by_port() API. xhci: Refactor bus suspend state into a struct. xhci: Index with a port array instead of PORTSC addresses. USB: Set usb_hcd->state and flags for shared roothubs. usb: Make core allocate resources per PCI-device. usb: Store bus type in usb_hcd, not in driver flags. usb: Change usb_hcd->bandwidth_mutex to a pointer. ...
