[alsa-devel] [PATCH 1/2] CHROMIUM: ASoC: Tegra: Move utilities to separate module

[Stephen Warren]

The utilities will be required by every machine driver. Including the
utility object directly into every machine driver causes a build failure
if the modules are actually built into the kernel, since each will define
the symbols exported by the utility file. Solve this by moving the
utility object into a separate module.
