usb gadget: link fixes for MIDI gadget
Change how the MIDI gadget driver builds: don't use separate compilation, since it works poorly when key parts are library code (with init sections etc). Instead be as close as we can to "gcc --combine ...". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
