Hi
Second 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 adds patch to include/acpi/acpi_bus.h that allow us to remove #if IS_ENABLED(CONFIG_ACPI) checks that were added in the first version.
Set goes on top linux-pm/linux-next commit e56b4d2.
First version here: http://mailman.alsa-project.org/pipermail/alsa-devel/2013-October/067737.htm...

Looks good to me. If there are no objections, I can merge these through my tree.
Which is basically fine with me. Do you want to have it in 3.13 already? I mean renaming the devices could lead to regressions, so I'd rather be conservative and aim for 3.14.
