Subject: [PATCH] ASoC: soc-core: find rtd via dai_link pointer at snd_soc_get_pcm_runtime()
Git-commit: 4468189ff307f294491628a49702a04de22bffb8
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

Current snd_soc_get_pcm_runtime() is finding rtd by checking dai_link
name. But, it is strange and waste of CPU power, because its user want
to get from rtd from dai_link, not from dai_link name.
This patch find rtd via dai_link pointer instead of its name.
