[PATCH] Usb gadget drivers 2.4 kernel

[John Carlson]

While developing a gadget driver for the 2.4 kernel, I
discovered this error in the gadget driver.  This bug
has been present since the gadget driver was back
ported from the 2.6 kernel.

Actually, it's just that one source file (config.c),
and the fix is in the gadget-2.4 tree already.  I'll
have to resubmit this one, it's rather annoying to
anyone trying to make sure their new hardware works!
