Follow-ups

--- Michael Hennerich 2009-03-18 12:39:38

Fixed on svn trunk:

Fix usb_gadget_register_driver don't test for unbind.

Unbind is declared __exit_p(f) which defaults to NULL if not MODULE

Fix compile warnings - WARN redefined

Use board defines to workaround board issues rather than processor

defines.

Fix Kconfig indention
