    ALSA: mark all struct bus_type as const · 66e82d21
    Greg Kroah-Hartman authored
    Now that the driver core can properly handle constant struct bus_type,
    move all of the sound subsystem struct bus_type structures as const,
    placing them into read-only memory which can not be modified at runtime.
    
    Note, this fixes a duplicate definition of ac97_bus_type, which somehow
    was declared extern in a .h file, and then static as a prototype in a .c
    file, and then properly later on in the same .c file.  Amazing that no
    compiler warning ever showed up for this.
