Merge tag 'sound-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai: "Very small fixes (all one-liners) at this time. One fix is for a PCM core stuff to correct the mmap behavior on non-x86. It doesn't show on most machines but mostly only for exotic non-interleaved formats" * tag 'sound-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: pcm: potential uninitialized return values ALSA: pcm: Use dma_bytes as size parameter in dma_mmap_coherent() ALSA: usb-audio: Add native DSD support for TEAC UD-301
