sound: remove OSS Ensoniq SoundScape driver
The OSS driver for Ensoniq SoundScape cards is broken after conversion to mutexes and a new ALSA snd-sscape driver handles all devices handled by the OSS one. The ALSA driver was tested with these cards: Spea V7 MediaFX Ensoniq Soundscape Elite Ensoniq Soundscape VIVO (this card is not handled by the OSS driver) Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Takashi Iwai <tiwai@suse.de>

293 Answer Y if you have a sound card based on the Ensoniq SoundScape
294 chipset. Such cards are being manufactured at least by Ensoniq, Spea
295 and Reveal (Reveal makes also other cards).
296
297 If you compile the driver into the kernel, you have to add
298 "sscape=<io>,<irq>,<dma>,<mpuio>,<mpuirq>" to the kernel command
299 line.
