ALSA: pci: rme: Set up buffer type properly
Although the regression of the mmap was fixed in the recent commit dc0dc8a73e8e ("ALSA: pcm: Fix mmap breakage without explicit buffer setup"), RME9652 and HDSP drivers have still potential issues with their mmap handling. Namely, they use the default mmap handler without the standard buffer preallocation, and PCM core wouldn't use the coherent DMA mapping. It's practically OK on x86, but on some exotic architectures, it wouldn't work. This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too. Link: https://lore.kernel.org/r/20210809071829.22238-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
