By default HDA sound card is registered with shortname "tegra-hda". Same driver is used across tegra platforms and it is necessary to distinguish between platforms to use platform specific settings from userspace. One such example is, hdmi port on different platforms use different alsa pcm device ID. For hdmi playback to work it should open correct pcm device depending on the platform. This patch applies shortname from first compatible string provided in root node of device tree. Userspace then can use this card name to apply specific settings.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
