 	src/sys/dev/isa: spkr_pcppi.c
 
 Log Message:
 Implement a common spkr_detach() function and call it from the
 attachment-specific detach functions.  Returns EBUSY if the
 device instance is busy, based on whether or not a sc->sc_inbuf
 is allocated.  The buffer is malloc()d at spkropen time, and is
 free()d in spkrclose().
 
 Now we can actually implement the MODULE_CMD_FINI command and
 unload the driver at will.
