Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * 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)
