[alsa-devel] alsa git: which version of ac97_codec.c am i supposed to hxr?

[John L. Utz III]

Hello All;

I feel confused by the presence of 2 different copies of ac97_codec.c:

   jutz-gnto ~ # find . -name ac97_codec.c
     ./alsa-driver/pci/ac97/ac97_codec.c
     ./alsa-kmirror/pci/ac97/ac97_codec.c

worse yet,they are not in sync:

jutz-gnto ~ # diff -w ./alsa-driver/pci/ac97/ac97_codec.c  
./alsa-kmirror/pci/ac97/ac97_codec.c

< #include "../../alsa-kernel/pci/ac97/ac97_id.h"

< #include "../../alsa-kernel/pci/ac97/ac97_patch.c"
---
> #include "ac97_patch.c"

< #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 0)
1929d1926
< #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 14)
1931d1927
< #endif
1953,1956d1948
< #else /* <= 2.6.0 */
< #define snd_ac97_dev_register NULL
< #define snd_ac97_dev_disconnect       NULL
< #endif


Which of these am i supposed to use? am i supposed to change both of them  
for some backward compatibility purpose?

tnx!
