[PATCH 4.15 08/72] ALSA: pcm: Use dma_bytes as size parameter in dma_mmap_coherent()

4.15-stable review patch. If anyone has any objections, please let me know. -- From: Stefan Roese commit 9066ae7ff5d89c0b5daa271e2d573540097a94fa upstream. When trying to use the driver (e.g. aplay *.wav), the 4MiB DMA buffer will get mmapp'ed in 16KiB chunks.
