[Patch 1/1] V4L (926) Saa7134 alsa can only be autoloaded aftersaa7134 is active
From: mchehab
Date: Mon Nov 07 2005 - 16:16:42 EST
From: Ricardo Cerqueira <v4l@xxxxxxxxxxxxx>
- Saa7134-alsa can only be autoloaded after saa7134 is active
- Applied pertinent changes proposed by the ALSA team
- dsp_nr replaced by ALSA's index[]
