When usbfs receives a ctrl-request from userspace it calls check_ctrlrecip, which for a request with USB_RECIP_ENDPOINT tries to map this to an interface to see if this interface is claimed, except for ctrl-requests with a type of USB_TYPE_VENDOR. When trying to use this device: http://www.akaipro.com/eiepro redirected to a Windows vm running on qemu on top of Linux. The windows driver makes a ctrl-req with USB_TYPE_CLASS and USB_RECIP_ENDPOINT with index 0, and the mapping of the endpoint (0) to the interface fails since ep 0 is the ctrl endpoint and thus never is part of an interface. This patch fixes this ctrl-req failing by skipping the checkintf call for USB_RECIP_ENDPOINT ctrl-reqs on the ctrl endpoint. Reported-by:

Wishbone is an open hardware SoC bus commonly used in FPGA designs. Bus access can be serialized using the Etherbone protocol <http://www.ohwr.org/projects/etherbone-core>. This driver is intended to be used with devices which attach their internal Wishbone bus to a USB serial interface using the Etherbone protocol. A userspace library is required to speak the protocol made available by this driver as ttyUSBx. Signed-off-by:

Just like the OHCI counter part we just can remove the architecture specific symbols which prevent these configuration symbols from being selected by platforms/architectures requiring it. The original implementation did not scale at all since it required each and every single architecture to be added for these configuration symbols to be selected. Now it is up to the EHCI driver and/or platform to select these configuration symbols accordingly. Acked-by:

Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd' and s5p_ehci is nothing but a pointer to hcd->priv; add hcd to the driver data rather than s5p_ehci.

Separate the Orion host controller driver from ehci-hcd host code into its own driver module because of following reason. With the multiplatform changes in arm-soc tree, it becomes possible to enable the mvebu platform (which uses ehci-orion) at the same time as other platforms that require a conflicting EHCI bus glue. At the moment, this results in a warning like drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable] and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e023203 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the orion bus glue. An earlier version of this patch was included in 3.9 but caused a regression there, which has subsequently been fixed. While we are here, use the opportunity to disabiguate the two Marvell EHCI controller implementations in Kconfig. In V4 (arnd): - Improve Kconfig text In V3: - More detail provided in commit message regarding this patch. - Replaced hcd_name string "ehci-orion" into "orion-ehci". - MODULE_LICENSE is GPL v2. - In ehci_init_driver calling second argument passed as NULL instead of ehci_orion_overrides because ehci_orion_overrides is removed.

There are no functional changes in this patch. However, because the compliance mode timer can be deleted in more than one function, it seemed expedient to include the function name in the debug strings. Also limited the use of capitals to the first word in the compliance mode debug messages, except after a function name where all words start with lower case, in keeping with the style prevalent elsewhere in xhci.c.

This patch adds support for kvm_gfn_to_hva_cache_init functions for reads and writes that will cross a page. If the range falls within the same memslot, then this will be a fast operation. If the range is split between two memslots, then the slower kvm_read_guest and kvm_write_guest are used. Tested: Test against kvm_clock unit tests. Signed-off-by:

tty_port_tty_get might return a tty which is NULL. But it is dereferenced unconditionally in edge_send. Stop dereferencing that by sending usb_serial_port pointer around. Signed-off-by:
