* [PATCH 1/1] ASoC: soc-component: add snd_soc_component_ack() [not found] <CGME20200403021943epcas2p36334748d486a0d4703fb12d88fbc9ee8@epcas2p3.samsung.com> @ 2020-04-03 2:19 ` Gyeongtaek Lee 0 siblings, 0 replies; 2+ messages in thread From: Gyeongtaek Lee @ 2020-04-03 2:19 UTC (permalink / raw) To: 'Mark Brown', kuninori.morimoto.gx Cc: alsa-devel, lgirdwood, tiwai, hmseo, cpgs, tkjung, pilsun.jang Current ALSA SoC is directly using component->driver->ops->xxx, thus, it is deep nested, and makes code difficult to read, and is not good for encapsulation. This patch adds new snd_soc_component_ack() and use it. Ack callback is revived because some ASoC driver is using it.
