Adding module to ALSA tree with Kconfig script

[Perry Gilfillan <perrye@linuxmail.org>]

Hello,

It seems that between alsa-driver-1.0.2 and 1.0.4, the 
scripts/Modules.dep file has been dropped in favour of Kconfig scripts. 
  This seems like a good thing, but I'm at a loss to get my snd-tvmixer 
to work by this method.

I've looked at the revised "Writing an ALSA Driver" chapter 14, and 
still can't get it straight.  The first hurdle is creating a Kconfig 
script in the alsa-kernel/i2c directory.  This is what I came up with:

   # ALSA I2C drivers

   menu "I2C devices"
           depends on SND!=n && I2C

   config SND_TVMIXER
           tristate "Video 4 Linux TV-Mixer"
           depends on SND
           help
             Say 'Y' or 'M' to include support for TV-Mixer.
                   This module requires that the V4L msp3400 module be
                   present.

   endmenu



Then I have added these lines to alsa-kernel/i2c/Makefile:

snd-tvmixer-objs := tvmixer.o
obj-$(CONFIG_SND_TVMIXER) += snd-tvmixer.o


Chapter 14 has the second line written as 'extra-obj-$( ....', so I 
tried it both ways.

I'm building against a 2.4.25 kernel, so how do I invoke the Kconfig 
scripts?  or do I need to RTFine kbuild Manual?

Thanks,

Perry
