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

Commit Message

Vijendar Mukunda Oct. 7, 2024, 8:53 a.m. UTC

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.
