From: Ranjani Sridharan Date: Tue, 2 Apr 2024 15:18:28 +0000 (-0500) Subject: ASoC: SOF: ipc4-topology: Save the ALH DAI index during hw_params X-Git-Tag: io_uring-6.10-20240523~78^2~3^2~95^2 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=f0caa4fc244ca739ce6d12168aa588c412c81190;p=linux-2.6-block.git ASoC: SOF: ipc4-topology: Save the ALH DAI index during hw_params The node_id for multi-gateway ALH DAI's get overwritten with the group_id during the DAI copier's ipc_prepare op. So, save the ALH dai_index during the BE DAI hw_params in the dai_index field of struct ipc4_copier and use that to set the device ID in the configuration blob. This will avoid errors during copier init after an xrun. Note that the dai_index is typically set in topology for DMIC/SSP, but it's not used for ALH. Reclaiming this dai_index field to store the node_id does not generate a conflict with topology-defined values.
