Linus,

please pull sound fixes for v4.15-rc5 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-4.15-rc5

The topmost commit is 5a15f289ee87eaf33f13f08a4909ec99d837ec5f

----------------------------------------------------------------

sound fixes for 4.15-rc5

All stable fixes here:
- A regression fix of USB-audio for the previous hardening patch
- A potential UAF fix in rawmidi
- HD-audio and USB-audio quirks, the missing new ID

Guneshwor Singh (1):
ALSA: hda - Add vendor id for Cannonlake HDMI codec

Jussi Laako (1):
ALSA: usb-audio: Add native DSD support for Esoteric D-05X

Kailang Yang (1):
ALSA: hda/realtek - Fix Dell AIO LineOut issue

Takashi Iwai (2):
ALSA: rawmidi: Avoid racy info ioctl via ctl device
ALSA: usb-audio: Fix the missing ctl name suffix at parsing SU
