[PATCH v2 1/3] ASoC: SDCA: export sdca_find_entity_by_label() helper

[shumingf]

From: Shuming Fan <shumingf@realtek.com>

Export the sdca_find_entity_by_label() helper so that codec drivers can
locate SDCA entities by their labels.

Be good to make sure you are CCing at least
patches@opensource.cirrus.com on SDCA patches, safer that I don't
