[alsa-devel] [PATCH] ASoC: Check for machine type in GTA01 machine driver

[Mark Brown]

Since there are now multiple OpenMoko platforms it is more important to
check that the machine driver is running on the correct system.  This
was orgininally generated as part of the initial GTA02 machine port.
