git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "The only significant core change is ASoC DPCM fix for asymmetric setup; other remaining changes are device-specific fixes, including the hardening of string manipulations.

2022-02-02ACPI / scan: Create platform device for CS35L41Lucas Tanure
The ACPI device with CSC3551 or CLSA0100 are sound cards with multiple instances of CS35L41 connected by I2C or SPI to the main CPU. We add an ID to the ignore_serial_bus_ids list to enumerate all I2C or SPI devices correctly. The same IDs are also added into serial-multi-instantiate so that the driver can correctly enumerate the ACPI.

2022-02-02platform/x86: serial-multi-instantiate: Add SPI supportStefan Binding
Add support for spi bus in serial-multi-instantiate driver Some peripherals can have either a I2C or a SPI connection to the host (but not both) but use the same HID for both types. So it is not possible to use the HID to determine whether it is I2C or SPI. The driver must check the node to see if it contains I2cSerialBus or SpiSerialBus entries. For backwards-compatibility with the existing nodes I2C is checked first and if such entries are found ONLY I2C devices are created. Since some existing nodes that were already handled by this driver could also contain unrelated SpiSerialBus nodes that were previously ignored, and this preserves that behavior. If there is ever a need to handle a node where both I2C and SPI devices must be instantiated this can be added in future.
