Use a more current logging style with dev_printk where possible. o Convert uses of US_DEBUGP to usb_stor_dbg o Add "struct us_data *" to usb_stor_dbg uses o usb_stor_dbg now uses struct device */dev_vprint_emit o Removed embedded function names o Coalesce formats o Remove trailing whitespace o Remove useless OOM messages o Remove useless function entry/exit logging o Convert some US_DEBUGP uses to dev_info and dev_dbg Object size is slightly reduced when debugging is enabled, slightly increased with no debugging because some initialization and removal messages are now always emitted.

Kill custom closing_wait implementation and let the tty-layer handle it instead.

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.

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.

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.

7edb3daf: (USB: EHCI: make ehci-s5p a separate driver) raised an issue with ehci-s5p's driver data. 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. This fixes issues with null pointer dereferencing in s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().

Separate the Qualcomm QSD/MSM on-chip host controller driver from ehci-hcd host code so that it can be built as a separate driver module. This work is part of enabling multi-platform kernels on ARM; however, note that other changes are still needed before Qualcomm QSD/MSM can be booted with a multi-platform kernel, which is not expected before 3.11. 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 msm bus glue. In V5 (arnd): - add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls In V3: - Detailed commit message added here describing why this patch is required. - Arranged #include's in alphabetical order. - driver.name initialized hcd_name[] = "ehci-msm" in platform_driver structure initialization instead of "msm-ehci", which was the reason why it broke in EHCI USB testing In V2: Tegra patch related changes removed from this patch.
