[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.

	users have complained indicating there is no more need for these

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.
