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

sound fixes for 5.3-rc5

All small fixes targeted for stable:

- Two fixes for USB-audio with malformed descriptor, spotted by
fuzzers
- Two fixes Conexant HD-audio codec wrt power management
- Quirks for HD-audio AMD platform and HP laptop
- HD-audio memory leak fix

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

Hui Peng (2):
ALSA: usb-audio: Fix an OOB bug in parse_audio_mixer_unit
ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_term

Hui Wang (2):
ALSA: hda - Let all conexant codec enter D3 when rebooting
ALSA: hda - Add a generic reboot_notify

Takashi Iwai (2):
ALSA: hda - Apply workaround for another AMD chip 1022:1487
ALSA: hda/realtek - Add quirk for HP Envy x360

Wenwen Wang (1):
ALSA: hda - Fix a memory leak bug
