[ALSA] ALS4000 update
Browse files Browse the repository at this point in the history 
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
