Subject: ASoC: SOF: Intel: hda: add SDCA property check
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bb6a3c2db281c7d5aaa79b2a6fa00bcd10c0bb8f;p=thirdparty%2Fkernel%2Flinux.git

ASoC: SOF: Intel: hda: add SDCA property check

If SDCA property is not present in the DisCo table, assume it
is present. This allows DAI links to be created from codec_info_list
instead of being skipped.
