Takashi Iwai 53e81668e1 ASoC: intel: atom: Fix breakage for PCM buffer address setup ... [ Upstream commit 65ca89c2b1 ] The commit 2e6b836312 ("ASoC: intel: atom: Fix reference to PCM buffer address") changed the reference of PCM buffer address to substream->runtime->dma_addr as the buffer address may change dynamically. However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.
