Patrick Mochel 45029c3207 [PATCH] oss: remove deprecated PM interface from opl3sa2 driver 
This change removes the old, deprecated interface from the opl3sa2 driver,
including the pm_{,un}register() calls, the local storage of the pmdev object
and the reference to the old header files.  This change is done to assist in
eradicating the users of the legacy interface so as to help facilitate the
removal of the interface itself.

/*
* sound/opl3sa2.c
*
* A low level driver for Yamaha OPL3-SA2 and SA3 cards.
* NOTE: All traces of the name OPL3-SAx have now (December 2000) been
* removed from the driver code, as an email exchange with Yamaha
* provided the information that the YMF-719 is indeed just a
* re-badged 715.
*
* Copyright 1998-2001 Scott Murray <scott@spiteful.org>
*
* Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen
* and others. Now incorporates code/ideas from pss.c, also by Hannu
* Savolainen. Both of those files are distributed with the following
* license:

*
* Change History
* --------------
* Scott Murray Original driver (Jun 14, 1998)
* Paul J.Y. Lahaie Changed probing / attach code order
* Scott Murray Added mixer support (Dec 03, 1998)
* Scott Murray Changed detection code to be more forgiving,
* added force option as last resort,
* fixed ioctl return values. (Dec 30, 1998)
* Scott Murray Simpler detection code should work all the time now
* (with thanks to Ben Hutchings for the heuristic),
* removed now unnecessary force option. (Jan 5, 1999)
* Christoph Hellwig Adapted to module_init/module_exit (Mar 4, 2000)
* Scott Murray Reworked SA2 versus SA3 mixer code, updated chipset
* version detection code (again!). (Dec 5, 2000)
* Scott Murray Adjusted master volume mixer scaling. (Dec 6, 2000)
* Scott Murray Based on a patch by Joel Yliluoma (aka Bisqwit),
* integrated wide mixer and adjusted mic, bass, treble
* scaling. (Dec 6, 2000)
* Scott Murray Based on a patch by Peter Englmaier, integrated
* ymode and loopback options. (Dec 6, 2000)
* Scott Murray Inspired by a patch by Peter Englmaier, and based on
* what ALSA does, added initialization code for the
* default DMA and IRQ settings. (Dec 6, 2000)
* Scott Murray Added some more checks to the card detection code,
* based on what ALSA does. (Dec 12, 2000)
* Scott Murray Inspired by similar patches from John Fremlin,
* Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4
* ISA PnP API support, mainly based on bits from
* sb_card.c and awe_wave.c. (Dec 12, 2000)
* Scott Murray Some small cleanups to the init code output.
* (Jan 7, 2001)
* Zwane Mwaikambo Added PM support. (Dec 4 2001)
*
* Adam Belay Converted driver to new PnP Layer (Oct 12, 2002)
* Zwane Mwaikambo Code, data structure cleanups. (Feb 15 2002)
* Zwane Mwaikambo Free resources during auxiliary device probe
* failures (Apr 29 2002)
