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