[PATCH v2 0/2] ASoC: Use DMI name in sound card long name

[mengdong.lin@linux.intel.com]

From: Mengdong Lin <mengdong.lin@linux.intel.com>

This series is based on Liam's idea to use DMI name as the sound card
short name in the audio workshop. Now we add DMI info to the card long
name:
- Not change the card name (short name), keep it simple. So the card ID
  won't change as well.
- Use DMI name to make the card long name.

Machine drivers can use a new API to get this feature.

In user space, when the sound server ask UCM to open a sound card, UCM
will try to find the best machine-specific configuration file based on
the card long name, and only if not avaiable, fallback to the default
configuration file that matches the card name (short name). 

Please see patch:
ucm: Automatically load the best config file based on the card long name

History:
  v1 from RFC: Give up using a table to map DMI info to a simple string,
        since we cannot maintain such a table for each machine. Just do
        verbatim copy of DMI info and let user space decide how to use the
        DMI info in card long name to find the best UCM config file.

        If device driver adds a flavor string, just append it after the
        DMI info fields to the card long name.

  v2:   Exclude card name and only keep DMI name in the long name, to
        save the space since the long name cannot exceed 80 characters.
	Trim special characters like SPACE in the long name, because UCM
        configuration files & directories may use the same long name and
        Autoconf cannot handle special characters.
