Subject: [PATCH] ASoC: soc-core: remove snd_soc_get_dai_substream()
Git-commit: 8babfb7030573f7338b141d038c2094b7bb95034
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
No driver is using snd_soc_get_dai_substream(),
and snd_soc_get_pcm_runtime() is enough for such purpose.
We can revival it if it was needed in the future.
Let's remove unused function.
