ALSA CVS update - Jaroslav Kysela <perex@suse.cz> 

ES18xx driver,ES1688 driver,GUS Classic driver,GUS Extreme driver
GUS MAX driver,AMD InterWave driver,SB16/AWE driver,SB8 driver
<davej@redhat.com>
This is a *really* silly one.  The various probing routines in these
drivers can return -ENODEV, -ENOMEM etc.. so when we do something like

cards += probe_routine()

In some situations we can end up with -13 sound cards, and other
such nonsense. Result : lots of fun oopses.
