Hi,

Yesterday I was trying to compile the latest snapshot of alsa-driver on 
top of kernel 2.6.28_rc8. When looking through the console output of 
make, I saw two warnings given by LD reporting two unknown symbols in 
snd-fm801.ko(driver for a ForteMedia sound card):

Building modules, stage 2.
  MODPOST 170 modules
WARNING: "snd_tea575x_init"

sound/pci/fm801.c:1447:         snd_tea575x_init(&chip->tea);

So this symbols are exported by tea575x-tuner.c. There's a card option parameter
in configuration of alsa-driver called 'fm801-tea575x-bool'.But eventhough, I'm configuring
the package with, "--with-card-options=all", I'm getting this warnings. As a consequence
it's impossible to load the module snd-fm801.

I think that it's a problem with Kconfig stuff but I really don't get how alsa-driver package
manages the whole thing with alsa-kernel directory, patchsets etc.(BTW, is there any documentation about
the mechanism in alsa-driver, and the functions of separate git repos alsa-driver, alsa-kernel, stub, etc.?)

I'm having the issue with
2.6.25.x && (1.0.17 || 1.0.18),
2.6.28_rc8 && (1.0.18)

so the problem may not be caught until this time because there exists a few distributions which ships
alsa-driver(and other kernel modules) separately.

Regards,
