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.

Kernel driver max127
====================
Author:
* Tao Ren <rentao.bupt@gmail.com>
Supported chips:
* Maxim MAX127
Prefix: 'max127'
Datasheet: https://datasheets.maximintegrated.com/en/ds/MAX127-MAX128.pdf
Description
-----------
The MAX127 is a multirange, 12-bit data acquisition system (DAS) providing
8 analog input channels that are independently software programmable for
a variety of ranges. The available ranges are {0,5V}, {0,10V}, {-5,5V}
and {-10,10V}.
The MAX127 features a 2-wire, I2C-compatible serial interface that allows
communication among multiple devices using SDA and SCL lines.

============== ==============================================================
in[0-7]_input The input voltage (in mV) of the corresponding channel.
RO
in[0-7]_min The lower input limit (in mV) for the corresponding channel.
ADC range and LSB will be updated when the limit is changed.
For the MAX127, it will be adjusted to -10000, -5000, or 0.
RW
in[0-7]_max The higher input limit (in mV) for the corresponding channel.
ADC range and LSB will be updated when the limit is changed.
For the MAX127, it will be adjusted to 0, 5000, or 10000.
