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
-----------
LM95233 and LM95234 are 11-bit digital temperature sensors with a 2-wire
System Management Bus (SMBus) interface and TrueTherm technology
that can very accurately monitor the temperature of two (LM95233)
or four (LM95234) remote diodes as well as its own temperature.
The remote diodes can be external devices such as microprocessors,
graphics processors or diode-connected 2N3904s. The chip's TruTherm
beta compensation technology allows sensing of 90 nm or 65 nm process
thermal diodes accurately.
All temperature values are given in millidegrees Celsius. Temperature
is provided within a range of -127 to +255 degrees (+127.875 degrees for
the internal sensor). Resolution depends on temperature input and range.
Each sensor has its own maximum limit, but the hysteresis is common to all
channels. The hysteresis is configurable with the tem1_max_hyst attribute and
affects the hysteresis on all channels. The first two external sensors also
have a critical limit.
The lm95234 driver can change its update interval to a fixed set of values.
It will round up to the next selectable interval. See the datasheet for exact
values. Reading sensor values more often will do no harm, but will return
'old' values.
