Here are a bunch of USB patches for 3.3-rc1.

Nothing major, largest thing here is the removal of some drivers that
did not work at all.  Other than that, the normal collection of bugfixes
and new device ids.

xHCI: Cleanup isoc transfer ring when TD length mismatch found

2012-01-25T20:55:19+00:00

When a TD length mismatch is found during isoc TRB enqueue, it directly
returns -EINVAL. However, isoc transfer is partially enqueued at this time,
and the ring should be cleared.

This should be backported to kernels as old as 2.6.36, which contain the
commit 522989a27c7badb608155b1f1dea3487ed431f74 "xhci: Fix failed
enqueue in the middle of isoch TD."

Revert "drivers: usb: Fix dependency for USB_HWA_HCD"

2012-01-24T23:33:44+00:00

This reverts commit 0dd2b62ada6f911fbd13e98e98f57f4edc42c604.

It causes a bunch of Kconfig errors:

drivers/usb/host/Kconfig:559:error: recursive dependency detected!
drivers/usb/host/Kconfig:559:	symbol USB_HWA_HCD depends on UWB
drivers/uwb/Kconfig:5:	symbol UWB is selected by USB_WUSB
drivers/usb/wusbcore/Kconfig:4:	symbol USB_WUSB is selected by USB_HWA_HCD

showing that this really wasn't the correct fix at all.

USB: OHCI: fix new compiler warnings

2012-01-24T20:24:06+00:00

This patch (as1515) fixes some unavoidably dumb compiler warnings:

  CC [M]  drivers/usb/renesas_usbhs/mod.o
In file included from drivers/usb/host/ohci-hcd.c:101:0:
drivers/usb/host/ohci-dbg.c: In function ‘fill_registers_buffer’:
drivers/usb/host/ohci-dbg.c:656:2: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]
drivers/usb/host/ohci-dbg.c:675:3: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]

Instead of trying to fix the macro to work under all cirumstances,
just add a second macro for use in cases where the "next" argument is
the address of a local variable.

Unfortunately the macro cannot be replaced by a real subroutine,
because there's no va_list version of ohci_dbg() or dev_dbg().

drivers/usb/host/ehci-fsl.c: add missing iounmap

2012-01-24T20:23:17+00:00

Add missing iounmap in error handling code, in a case where the function
already preforms iounmap on some other execution path.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
expression e;
statement S,S1;
int ret;
@@
e = \(ioremap\|ioremap_nocache\)(...)
... when != iounmap(e)
if (<+...e...+>) S
... when any
    when != iounmap(e)
*if (...)
   { ... when != iounmap(e)
     return ...; }
... when any
iounmap(e);
//

ARM/USB: at91/ohci-at91: rename vbus_pin_inverted to vbus_pin_active_low

Allows to configure independently the vbus_pin associated with each port.
Matches usual naming scheme.
