[PATCHv4 0/3] I2C and SPI dev_name change for ACPI enumerated slaves

v4:
This version adds and uses acpi_dev_name() accessor instead defining
struct acpi_device stub for !CONFIG_ACPI

v3:
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"
in git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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 acpi_dev_name accessor for struct acpi_device device
name
i2c: Use stable dev_name for ACPI enumerated I2C slaves
spi: Use stable dev_name for ACPI enumerated SPI slaves
