  13  *
  14  * Thomas Sailer        ioctl code reworked (vmalloc/vfree removed)
  15  * Alan Cox             modularisation, clean up.
  16  *
  17  * 98-02-21: Vladimir Michl <vladimir.michl@upol.cz>
  18  *          Added mixer device for Beethoven ADSP-16 (master volume,
  19  *          bass, treble, synth), only for speakers.
  20  *          Fixed bug in pss_write (exchange parameters)
  21  *          Fixed config port of SB
  22  *          Requested two regions for PSS (PSS mixer, PSS config)
  23  *          Modified pss_download_boot
  24  *          To probe_pss_mss added test for initialize AD1848
  25  * 98-05-28: Vladimir Michl <vladimir.michl@upol.cz>
  26  *          Fixed computation of mixer volumes
  27  * 04-05-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
  28  *          Added code that allows the user to enable his cdrom and/or
  29  *          joystick through the module parameters pss_cdrom_port and
  30  *          pss_enable_joystick.  pss_cdrom_port takes a port address as its
  31  *          argument.  pss_enable_joystick takes either a 0 or a non-0 as its
  32  *          argument.
  33  * 04-06-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
  34  *          Separated some code into new functions for easier reuse.
  35  *          Cleaned up and streamlined new code.  Added code to allow a user
  36  *          to only use this driver for enabling non-sound components
  37  *          through the new module parameter pss_no_sound (flag).  Added
  38  *          code that would allow a user to decide whether the driver should
  39  *          reset the configured hardware settings for the PSS board through
  40  *          the module parameter pss_keep_settings (flag).   This flag will
  41  *          allow a user to free up resources in use by this card if needbe,
  42  *          furthermore it allows him to use this driver to just enable the
  43  *          emulations and then be unloaded as it is no longer needed.  Both
  44  *          new settings are only available to this driver if compiled as a
  45  *          module.  The default settings of all new parameters are set to
  46  *          load the driver as it did in previous versions.
  47  * 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
  48  *          Added module parameter pss_firmware to allow the user to tell
  49  *          the driver where the firmware file is located.  The default
  50  *          setting is the previous hardcoded setting "/etc/sound/pss_synth".
  51  * 00-03-03: Christoph Hellwig <chhellwig@infradead.org>
  52  *          Adapted to module_init/module_exit
  53  * 11-10-2000: Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
  54  *          Added __init to probe_pss(), attach_pss() and probe_pss_mpu()
  55  * 02-Jan-2001: Chris Rankin
  56  *          Specify that this module owns the coprocessor
