[PATCH 3/3] ASoC: amd: acp: refactor sof_card_dai_links_create() function

From: Vijendar Mukunda
Date: Mon Oct 07 2024 - 04:54:46 EST


Refactor sof_card_dai_links_create() function by replacing
'sof_ends' and 'sof_dais' structure declarations as
struct asoc_sdw_endpoint *sof_ends __free(kfree) = NULL;
struct asoc_sdw_dailink *sof_dais __free(kfree) = NULL;
Use above declarations to eliminate goto statements usage.
