From d12ca6d4c31bf974ecc80e36761488f41d05d18b Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Mon, 20 Jan 2025 16:19:37 +0800 Subject: [PATCH] ASoC: fsl_asrc_m2m: only handle pairs for m2m in the suspend ASRC memory to memory cases and memory to peripheral cases are sharing the same pair pools, the pairs got for m2m suspend function may be used for memory to peripheral, which is handled memory to peripheral driver and can't be handled in memory to memory suspend function. Use the "pair->dma_buffer" as a flag for memory to memory case, when it is allocated, handle the suspend operation for the related pairs.
