[PATCH v2 4/6] ASoC: Intel: sof_sdw: remove hard-coded codec_conf table
Kai Vehmanen

Wed Sep 23 19:33:56 CEST 2020
From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>
Now that the ACPI machine params provide all the information needed,
allocate the card codec_conf dynamically and set .dlc and
.prefix_name.
