That's because the driver doesn't support being compiled as a module.
The Kconfig, as *I* wrote it, only allows for in-kernel compilation.

The only way you could have gotten my drivers to compile as a module
is if you hacked the Kconfig.

The ASoC V2 version of the driver supports loading as a module.  ASoC
V1 does not support loading sound drivers as modules, which is why I
didn't implement that support in the V1 drivers.  The 2.6.27 kernel
has ASoC V1.  ASoC V2 won't be integrated into the mainline until at
least 2.6.29, and maybe even 2.6.30.  The ASoC V2 repository is
available at http://opensource.wolfsonmicro.com/cgi-bin/gitweb.cgi?p=linux-2.6-asoc.git
under the asoc-v2-dev branch.
