[ALSA] ALS4000 update
Modules: SB drivers,ALS4000 driver some update for the ALS4000 driver (tested with hardware in my PC): - use common control names according to ControlNames.txt - add some controls (Master Mono, 3D control) - optimize struct snd_card_als4000_t layout (performance/size) - save some bytes via unified error path - constify some read-only data - add ToDo list - move GPL license text to top - add comments Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
