Pull sound fixes from Takashi Iwai: "Again it became bigger than wished, unfortunately, as this contains quite a few ASoC fixes that came up a bit late. It also includes yet more HD- and USB-audio quirks: I decided to merge them now, as those are for stable, and we'll need them sooner or later. Although the volumes are a bit high, all changes are device-specific (and reasonably small) fixes, so it should be safe for the late rc" * tag 'sound-5.15-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: usb-audio: Fix microphone sound on Jieli webcam.

Description
-----------
[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
accurately monitor (+/-2.5%) one current channel using a dedicated high-side
current-sense amplifier. The MAX16065 manages up to twelve system voltages
simultaneously, and the MAX16066 manages up to eight supply voltages.
The MAX16067 flash-configurable system manager monitors and sequences multiple
system voltages. The MAX16067 manages up to six system voltages simultaneously.
The MAX16068 flash-configurable system manager monitors and manages up to six
system voltages simultaneously.
The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
one current channel using a dedicated high-side current-sense amplifier. The
MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
monitors up to eight supply voltages.
Each monitored channel has its own low and high critical limits. MAX16065,
MAX16066, MAX16070, and MAX16071 support an additional limit which is
configurable as either low or high secondary limit. MAX16065, MAX16066,
MAX16070, and MAX16071 also support supply current monitoring.
Usage Notes
-----------
This driver does not probe for devices, since there is no register which
can be safely used to identify the chip. You will have to instantiate
the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
details.
WARNING: Do not access chip registers using the i2cdump command, and do not use
any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
supported by this driver interpret any access to a command register (including
read commands) as request to execute the command in question. This may result in
power loss, board resets, and/or Flash corruption. Worst case, your board may
turn into a brick.
