+
+commit 7de7c7d2cb49900e0b967be871bf695c7d6135c9 upstream.
+
+wMaxPacketSize is __le16 and should be accessed as such. Also fix the
+wBytesPerInterval assignment while here.
+
+v2: also fix the wBytesPerInterval assigment, noticed by Matt Evans
+
+This patch should be backported to the 3.0 kernel.

+Subject: usb: musb: fix oops on musb_gadget_pullup
+
+From: John Stultz <john.stultz@linaro.org>
+
+commit 72c487dfb94d02025fb7437dfe2314d836d5a9ab upstream.
+
+an 'unhandled fault' is causes when a gadget driver calls
+usb_gadget_connect() while the USB cable isn't plugged into
+the OTG port.
+
+the fault is caused by an access to MUSB's memory space
+while its clock is turned off due to pm_runtime kicking
+in.
+
+in order to fix the fault, we enclose musb_gadget_pullup()
+with pm_runtime_get_sync() ... pm_runtime_put() calls to
+be sure we will always reach that path with clock turned on.

+From: Andrew Bird <ajb@spheresystems.co.uk>
+
+commit 07b21fd83606263fe6f327b98774d51e13e502fd upstream.
+
+This patch adds the product ID of Huawei's Vodafone K3770 mobile broadband
+modem to option.c. This is necessary so that the driver gets loaded on demand
+without the intervention of usb_modeswitch. This has the benefit of it becoming
+available faster and also ensures that the option driver is not bound to a
+network interface that should be claimed by cdc_ether.

+commit a871e4f5519d8c52430052e1d340dd5710eb5ad6 upstream.
+
+Connecting the V2M to a Linux host results in a constant stream of
+errors spammed to the console, all of the form
+
+ sd 1:0:0:0: ioctl_internal_command return code = 8070000
+ : Sense Key : 0x4 [current]
+ : ASC=0x0 ASCQ=0x0
+
+The errors appear to be otherwise harmless. Add an unusual_devs entry
+which eliminates all of the error messages.

+Subject: USB: xhci: fix OS want to own HC
+
+From: JiSheng Zhang <jszhang3@gmail.com>
+
+commit 6768458b17f9bf48a4c3a34e49b20344091b5f7e upstream.
+
+Software should set XHCI_HC_OS_OWNED bit to request ownership of xHC.
+
+This patch should be backported to kernels as far back as 2.6.31.

+Subject: xhci: Don't submit commands or URBs to halted hosts.
+
+From: Sarah Sharp <sarah.a.sharp@linux.intel.com>
+
+commit 7bd89b4017f46a9b92853940fd9771319acb578a upstream.
+
+Commit fccf4e86200b8f5edd9a65da26f150e32ba79808
+"USB: Free bandwidth when usb_disable_device is called" caused a bit of an
+issue when the xHCI host controller driver is unloaded. It changed the
+USB core to remove all endpoints when a USB device is disabled. When the
+driver is unloaded, it will remove the SuperSpeed split root hub, which
+will disable all devices under that roothub and then halt the host
+controller. When the second High Speed split roothub is removed, the USB
+core will attempt to disable the endpoints, which will submit a Configure
+Endpoint command to a halted host controller.
+
+The command will eventually time out, but it makes the xHCI driver unload
+take *minutes* if there are a couple of USB 1.1/2.0 devices attached. We
+must halt the host controller when the SuperSpeed roothub is removed,
+because we can't allow any interrupts from things like port status
+changes.
+
+Make several different functions not submit commands or URBs to the host
+controller when the host is halted, by adding a check in
+xhci_check_args(). xhci_check_args() is used by these functions:
+
+xhci.c-int xhci_urb_enqueue()
+xhci.c-int xhci_drop_endpoint()
+xhci.c-int xhci_add_endpoint()
+xhci.c-int xhci_check_bandwidth()
+xhci.c-void xhci_reset_bandwidth()
+xhci.c-static int xhci_check_streams_endpoint()
+xhci.c-int xhci_discover_or_reset_device()
+
+It's also used by xhci_free_dev(). However, we have to take special
+care in that case, because we want the device memory to be freed if the
+host controller is halted.
+
+This patch should be backported to the 2.6.39 and 3.0 kernel.
