Subject: [PATCH] ASoC: soc-core: care .ignore_suspend for Component suspend
Git-commit: 1272063a7ee4e60ace4cf7cae621fb6f8cafaaba
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Card dai_link has .ignore_suspend, and ALSA SoC cares it when suspend.
For example, like this
for_each_card_rtds(card, rtd) {
if (rtd->dai_link->ignore_suspend)
continue;
...
}
But in snd_soc_suspend(), it doesn't care about
it when suspending Component. This patch cares it.
