[alsa-devel] [PATCHv3 0/3] I2C and SPI dev_name change for ACPI enumerated slaves

Third version of the set that changes I2C and SPI slave device names
to be generated from stable ACPI device names on ACPI 5 based systems
instead of using bus numbers which could change.
Slave device name change goes as
"x-00yz" -> "i2c-INTABCD:ij"
"spix.y" -> "spi-INTABCD:ij"
This version is actually a bit cleaner thanks to Rafael's
"ACPI / driver core: Store an ACPI device pointer in struct acpi_dev_node"
Set goes on top of linux-pm/linux-next due dependency to 1/3. As we are now
in merge-window I'm fine if 1/3 goes in first and I queue 2-3/3 later
to i2c and spi trees.
Jarkko Nikula (3):
ACPI: Provide struct acpi_device stub for !CONFIG_ACPI builds
i2c: Use stable dev_name for ACPI enumerated I2C slaves
spi: Use stable dev_name for ACPI enumerated SPI slaves
