Takashi Iwai b9d4a89935 ALSA: pci: rme: Fix unaligned buffer addresses ... commit 43d35ccc36 upstream. The recent fix for setting up the DMA buffer type on RME drivers tried to address the non-standard memory managements and changed the DMA buffer information to the standard snd_dma_buffer object that is allocated at the probe time. However, I overlooked that the RME drivers handle the buffer addresses based on 64k alignment, and the previous conversion broke that silently. This patch is an attempt to fix the regression. The snd_dma_buffer objects are copied to the original data with the correction to the aligned accesses, and those are passed to snd_pcm_set_runtime_buffer() helpers instead. The original snd_dma_buffer objects are managed by devres, hence they'll be released automagically.
