[PATCH 1/2] ASoC: amd: acp: update dmic_num logic for acp pdm dmic
From: Vijendar Mukunda
Date: Mon Mar 30 2026 - 03:25:42 EST
Currently there is no mechanism to read dmic_num in mach_params
structure. In this scenario mach_params->dmic_num check always
returns 0 which fails to add component string for dmic.
Update the condition check with acp pdm dmic quirk check and
pass the dmic_num as 1.
Fixes: 2981d9b0789c ("ASoC: amd: acp: add soundwire machine driver for legacy stack")
