[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.

- *
- * sound/wavfront.c
- *
- * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
- *
- * This driver supports the onboard wavetable synthesizer (an ICS2115),
- * including patch, sample and program loading and unloading, conversion
- * of GUS patches during loading, and full user-level access to all
- * WaveFront commands. It tries to provide semi-intelligent patch and
- * sample management as well.
- *
- * It also provides support for the ICS emulation of an MPU-401.  Full
- * support for the ICS emulation's "virtual MIDI mode" is provided in
- * wf_midi.c.
- *
- * Support is also provided for the Tropez Plus' onboard FX processor,
- * a Yamaha YSS225. Currently, code exists to configure the YSS225,
- * and there is an interface allowing tweaking of any of its memory
- * addresses. However, I have been unable to decipher the logical
- * positioning of the configuration info for various effects, so for
- * now, you just get the YSS225 in the same state as Turtle Beach's
- * "SETUPSND.EXE" utility leaves it.
- *
- * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
- * This chip also controls the configuration of the card: the wavefront
- * synth is logical unit 4.
- *
- *
- * Supported devices:
- *
- *   /dev/dsp                      - using cs4232+ad1848 modules, OSS compatible
- *   /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
- *   /dev/synth00                  - raw synth interface
- *

- *
- * Absolutely NO thanks to Turtle Beach/Voyetra and Yamaha for their
- * complete lack of help in developing this driver, and in particular
- * for their utter silence in response to questions about undocumented
- * aspects of configuring a WaveFront soundcard, particularly the

-Things here are weird. All data written to the board cannot

-potentially > 0x7F (127) must be split across multiple bytes.
-
-Sometimes, we need to munge numeric values that are represented on
-the x86 side as 8-32 bit values. Sometimes, we need to munge data
-that is represented on the x86 side as an array of bytes. The most
-efficient approach to handling both cases seems to be to use 2
-different functions for munging and 2 for de-munging. This avoids
-weird casting and worrying about bit-level offsets.

-		   is done purely at user level: there is no WFB parser in
-		   this driver, and so a complete reset (back to General MIDI,
-		   or theoretically some other configuration) is the
-		   responsibility of the user level library. 
-
