This breaks the build for me on an x86-64 allmodconfig:
/mnt/kernel/sound/soc/amd/renoir/acp3x-pdm-dma.c: In function 'acp_pdm_dma_hw_params':
/mnt/kernel/sound/soc/amd/renoir/acp3x-pdm-dma.c:245:18: error: 'runtime' undeclared (first use in this function); did you mean 'vtime'?
rtd->dma_addr = runtime->dma_addr;
^~~~~~~
vtime
