From cee28113db17f0de58df0eaea4e2756c404ee01f Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 19 Mar 2024 10:22:36 +0200 Subject: ASoC: dmaengine_pcm: Allow passing component name via config At the moment we cannot instantiate two dmaengine_pcms with the same parent device, as the components will be named the same, leading to conflicts. Add 'name' field to the snd_dmaengine_pcm_config, and use that (if defined) as the component name instead of deriving the component name from the device.
