[PATCH] add EXPORT_SYMBOL_GPL_FUTURE() to USB subsystem 

The USB core symbols will be converted to GPL-only in a few years.  Mark
this as such and update the documentation explaining why, and provide a
pointer for developers to receive help if they need it.

@ -196,3 +196,21 @@ Why: Board specific code doesn't build anymore since ~2.6.0 and no
users have complained indicating there is no more need for these
boards. This should really be considered a last call.

---------------------------
What: USB driver API moves to EXPORT_SYMBOL_GPL
When: Febuary 2008
Files: include/linux/usb.h, drivers/usb/core/driver.c
Why: The USB subsystem has changed a lot over time, and it has been
possible to create userspace USB drivers using usbfs/libusb/gadgetfs
that operate as fast as the USB bus allows. Because of this, the USB
subsystem will not be allowing closed source kernel drivers to
register with it, after this grace period is over. If anyone needs
any help in converting their closed source drivers over to use the
userspace filesystems, please contact the
linux-usb-devel@lists.sourceforge.net mailing list, and the developers
there will be glad to help you out.
