[PATCH] The scheduled removal of some OSS drivers
This patch contains the scheduled removal of OSS drivers that: - have ALSA drivers for the same hardware without known regressions and - whose Kconfig options have been removed in 2.6.17.

- * Special thanks to David C. Niemi, Jan Pfeifer
- *
- *
- * Module command line parameters:
- * none so far
- *
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * The card has both an FM and a Wavetable synth, but I have to figure
- * out first how to drive them...
- *
- * Revision history
- * 06.05.98 0.1 Initial release
- * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in cm_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.98 0.4 Don't allow excessive interrupt rates
- * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.98 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.98 0.7 Fix realplayer problems - dac.count issues
- * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.99 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 18.08.99 1.5 Only deallocate DMA buffer when unloading.
- * 02.09.99 1.6 Enable SPDIF LOOP
- * Change the mixer read back
- * 21.09.99 2.33 Use RCS version as driver version.
- * Add support for modem, S/PDIF loop and 4 channels.
- * (8738 only)
- * Fix bug cause x11amp cannot play.
- *
- * Fixes:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * 18/05/2001 - .bss nitpicks, fix a bug in set_dac_channels where it
- * was calling prog_dmabuf with s->lock held, call missing
- * unlock_kernel in cm_midi_release
- * 08/10/2001 - use set_current_state in some more places
- *
- * Carlos Eduardo Gorges <carlos@techlinux.com.br>
- * Fri May 25 2001
- * - SMP support ( spin[un]lock* revision )
- * - speaker mixer support
- * Mon Aug 13 2001
- * - optimizations and cleanups
- *
- * 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de>
- * Simon Braunschmidt <brasimon@web.de>
- * Sat Jan 31 2004
- * - provide support for opl3 FM by releasing IO range after initialization
- *
- * ChenLi Tien <cltien@cmedia.com.tw>
- * Mar 9 2004
- * - Fix S/PDIF out if spdif_loop enabled
- * - Load opl3 driver if enabled (fmio in proper range)
- * - Load mpu401 if enabled (mpuio in proper range)
- * Apr 5 2004
- * - Fix DUAL_DAC dma synchronization bug
- * - Check exist FM/MPU401 I/O before activate.
- * - Add AFTM_S16_BE format support, so MPlayer/Xine can play AC3/mutlichannel
- * on Mac
- * - Change to support kernel 2.6 so only small patch needed
- * - All parameters default to 0
- * - Add spdif_out to send PCM through S/PDIF out jack
- * - Add hw_copy to get 4-spaker output for general PCM/analog output
- *
- * Stefan Thater <stefan.thaeter@gmx.de>
- * Apr 5 2004
- * - Fix mute single channel for CD/Line-in/AUX-in
