[PATCH v4 2/8] usb/gadget: rndis: convert into module

In order to convert to configfs the usb functions need to be converted to a new interface and compiled as modules. This patch creates an rndis module which will be used by the new functions. After all users of f_rndis are converted to the new interface, this module can be merged with f_rndis module

[PATCH] usbfs: Increase arbitrary limit for USB 3 isopkt length

It's horrible coding style to panic the kernel when someone passes you an argument value you didn't expect. This patch should be backported to kernels as old as 2.6.31, that contain the commit d115b04818e57bdbc7ccde4d0660b15e33013dc8 "USB: xhci: Support for 64-byte contexts". Signed-off-by: Sarah

[RFC 4/6] xhci: remove BUG() in xhci_get_endpoint_type()

From: Mathias Nyman If the endpoint type is unknown, set it to 0 and fail gracefully instead of causing a kernel panic. This patch should be backported to kernels as old as 2.6.31, that contain the commit f94e0186312b0fc39f41eed4e21836ed74b7efe1 "USB: xhci: Bandwidth allocation support" Signed-

[RFC 6/6] usb: check usb_hub_to_struct_hub() return value

From: Mathias Nyman usb_hub_to_struct_hub() can return NULL in the unlikely cases a hub without active configuration, or a hub without ports is found. Even if unlikely we need to handle those cases properly. [Note from Sarah: I'm not sure which stable kernels need parts of this patch applied.

[RFC 5/6] xhci: check for failed dma pool allocation

From: Mathias Nyman Fail and free the container context in case dma_pool_alloc() can't allocate the raw context data part of it This patch should be backported to kernels as old as 2.6.31, that contain the commit d115b04818e57bdbc7ccde4d0660b15e33013dc8 "USB: xhci: Support for 64-byte contexts".

[RFC 3/6] xhci: Remove BUG in xhci_setup_addressable_virt_dev

From: Mathias Nyman We may have more speed types in the future, so fail gracefully, rather than causing the kernel to panic. BUG() was called if the device speed was unknown when setting max packet size. Set the max packet size at the same time as the slot speed and get rid of one switch statem

[RFC 2/6] xhci: Remove BUG_ON in xhci_get_input_control_ctx.

Fail gracefully, instead of causing the kernel to panic, if the input control context doesn't have the right type (XHCI_CTX_TYPE_INPUT). Push finding the pointer to the input control context up into functions that can fail. This patch should be backported to kernels as old as 2.6.31, that contain

[PATCH] usb: xhci: Fix Command Ring Stopped Event handling

The current XHCI code treats a command completion event with the COMP_CMD_STOP code as a slightly different version of COMP_CMD_ABORT. In particular, it puts the pointed-to command TRB through the normal command completion handlers. This is not how this event works. As XHCI spec 4.6.1.1 describes,

[PATCH] usb: xhci: Use non-interruptible sleep for XHCI commands

The XHCI stack usually uses wait_for_completion_interruptible_timeout() to wait for the completion of an XHCI command, and treats both timeouts and interruptions as errors. This is a bad idea, since these commands are often essential for the correct operation of the USB stack, and their failure can

[PATCH] ARM: OMAP4: USB_EHCI_HCD needs USB_PHY and NOP_USB_XCEIV

On OMAP4 platforms, EHCI HCD needs the physical layer signalling activated, along with the NOP USB Transceiver driver. Otherwise, the kernel boots without registering any USB device. This patch applies to Linux 3.10-rc2. Signed-off-by: Adrien Vergé --- diff --git a/drivers/usb/host/Kconfig b/dri
