The driver_name="tegra" is now required by the newer ALSA UCMs, otherwise Tegra UCMs don't match by the path/name. All Tegra machine drivers are specifying the card's name, but it has no effect if model name is specified in the device-tree since it overrides the card's name. We need to set the driver_name to "tegra" in order to get a usable lookup path for the updated ALSA UCMs. The new UCM lookup path has a form of driver_name/card_name. The old lookup paths that are based on driver module name continue to work as before. Note that UCM matching never worked for Tegra ASoC drivers if they were compiled as built-in, this is fixed by supporting the new naming scheme.
