USB 3 and Wireless USB specify a logarithmic encoding of the endpoint interval that matches the USB 2 specification. usb_fill_int_urb() didn't know that and was filling in the interval as if it was USB 1.1. Fix usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case alone, because David Vrabel wants to keep the old encoding. Update the struct urb kernel doc to note that SuperSpeed URBs must have urb->interval specified in microframes. Add a missing break statement in the usb_submit_urb() interrupt URB checking, since wireless USB and SuperSpeed USB encode urb->interval differently. This allows xHCI roothubs to actually register with khubd. Signed-off-by:

This patch removes a double usb_control_msg that sets the cp210x configuration registers a second time when calling cp210x_set_config. For data sizes >2 the second write gets corrupted. The patch has been created against 2.6.34-rc1, but all cp210x driver revisions are affected. Signed-off-by:

Contrary to the comment in fsg_add, fsg_bind calls fsg_unbind on errors, which decreases refcount and frees the fsg_dev structure, causing trouble when fsg_add does the same. Fix it by simply leaving up cleanup to fsg_add(). Signed-off-by:

The recent commit (0e530b45) that moved usb_ep_autoconfig from the __devinit section to the __init section missed the mass storage device. Its fsg_bind() function uses the usb_ep_autoconfig() function from non __init context leading to: WARNING: drivers/usb/gadget/g_mass_storage.o(.text): Section mismatch in reference from the function _fsg_bind() to the function .init.text:_usb_ep_autoconfig() So move fsg_bind() into __init as well.

The recent change to clean out dead gadget drivers (90f79768) missed the call to gadget_is_musbhsfc() behind CONFIG_BLACKFIN. This causes Blackfin gadget builds to fail since the function no longer exists anywhere. Signed-off-by:

"dev" is always null here. In the end it's only used to get the pci_name() of "pdev" which is redundant information and so I removed it. Signed-off-by:

The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY. However, it has no ULPI support - so there are no registers at all. That means accesses to ULPI_BUSCONTROL have to be abstracted away like other MUSB registers. This fixes building for Blackfin parts again. Signed-off-by:

CONFIG_ARCH_OMAP34XX is now CONFIG_ARCH_OMAP3. But since drivers/usb/musb/omap2430.c use CONFIG_PM for these registers and functions, do the same for the header. Otherwise we get the following for most omap3 defconfigs: drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'while' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'while' Signed-off-by:Tony Lindgren <tony@atomide.com> Signed-off-by:

The recent commit "usb: musb: Fix for isochronous IN transfer" (f82a689f) seems to have been against an older kernel version. It uses the old style naming of variables. Unfortunately, this breaks building for most MUSB users out there since "bDesiredMode" has been renamed to "desired_mode". Signed-off-by:

Clemens Ladisch authored
The EHCI driver stores in usb_host_endpoint.hcpriv a pointer to either an ehci_qh or an ehci_iso_stream structure, and uses the contents of the hw_info1 field to distinguish the two cases. After ehci_qh was split into hw and sw parts, ehci_iso_stream must also be adjusted so that it again looks like an ehci_qh structure. This fixes a NULL pointer access in ehci_endpoint_disable() when it tries to access qh->hw->hw_info1. Signed-off-by:

When isochronous URBs are shorter than one frame and when more than one ITD in a frame has been completed before the interrupt can be handled, scan_periodic() completes the URBs in the order in which they are found in the descriptor list. Therefore, the descriptor list must contain the ITDs in the correct order, i.e., a new ITD must be linked in after any previous ITDs of the same endpoint. This should fix garbled capture data in the USB audio drivers. Signed-off-by:

It is possible to have a multi-port device with a port lacking an in or out bulk endpoint. Only checking for num_bulk_in or num_bulk_out is thus not sufficient to determine whether a specific port has an in or out bulk endpoint. This fixes potential null pointer dereferences in the generic open and write routines, as well as access to uninitialised fifo in write_room and chars_in_buffer. Also let write fail with ENODEV (instead of 0) on missing out endpoint (also on zero-length writes). Signed-off-by:
