USB fixes for 3.7-rc2

Browse Source 
Here are the USB patches against your 3.7-rc1 tree.
 
 There are the usual UABI header file movements, and we finally are now
 able to remove the dbg() macro that is over 15 years old (that had to
 wait for after some other trees got merged into yours during the big
 3.7-rc1 merge window.)
 
 Other than that, nothing major, just a number of bugfixes and new device
 ids.  It turns out that almost all of the usb-serial drivers had bugs in
 how they were handling their internal data, leaking memory, hence all of
 those fixups.

/*
* This file holds USB constants and structures that are needed for
* USB device APIs. These are used by the USB device model, which is
* defined in chapter 9 of the USB 2.0 specification and in the
* Wireless USB 1.0 (spread around). Linux has several APIs in C that
* need these:
*
* - the master/host side Linux-USB kernel driver API;
* - the "usbfs" user space API; and
* - the Linux "gadget" slave/device/peripheral side driver API.
*
* USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
* act either as a USB master/host or as a USB slave/device. That means
* the master and slave side APIs benefit from working well together.
*
* There's also "Wireless USB", using low power short range radios for
* peripheral interconnection but otherwise building on the USB framework.
*
* Note all descriptors are declared '__attribute__((packed))' so that:
*
* [a] they never get padded, either internally (USB spec writers
* probably handled that) or externally;
*
* [b] so that accessing bigger-than-a-bytes fields will never
* generate bus errors on any platform, even when the location of
* its descriptor inside a bundle isn't "naturally aligned", and
*
* [c] for consistency, removing all doubt even when it appears to
* someone that the two other points are non-issues for that
* particular descriptor type.
