  10  * version: 1.5
  11  * status: beta
  12  * date: 2003/07/15
  13  *
  14  * Changes:
  15  *      Oleg Drokin: Some cleanup of load/unload functions.     1998/11/24
  16  *
  17  *      Thorsten Knabe: attach and unload rewritten,
  18  *      some argument checks added                              1998/11/30
  19  *
  20  *      Thorsten Knabe: Buggy isa bridge workaround added       1999/01/16
  21  *
  22  *      David Moews/Thorsten Knabe: Introduced options
  23  *      parameter. Added slightly modified patch from
  24  *      David Moews to disable dsp audio sources by setting
  25  *      bit 0 of options parameter. This seems to be
  26  *      required by some Aztech/Newcom SC-16 cards.             1999/04/18
  27  *
  28  *      Christoph Hellwig: Adapted to module_init/module_exit.  2000/03/03
  29  *
  30  *      Christoph Hellwig: Added isapnp support                 2000/03/15
  31  *
  32  *      Arnaldo Carvalho de Melo: get rid of check_region       2001/10/07
  33  *
  34  *      Thorsten Knabe: Compiling with CONFIG_PNP enabled
  35  *      works again. It is now possible to use more than one
  36  *      AD1816 sound card. Sample rate now may be changed during
  37  *      playback/capture. printk() uses log levels everywhere.
  38  *      SMP fixes. DMA handling fixes.
  39  *      Other minor code cleanup.                               2003/07/15
