Hi We've run into problem of changing I2C device names while developing ALSA SoC drivers for x86 based systems. Changing device names makes more difficult to match devices by their name. Which is what we use within ASoC subsystem. These changing names comes from changing adapter/bus numbering which could occur due variable amount of bus controllers, probe order, add-on cards or different BIOS settings. Patches here try to solve the problem on ACPI 5 based systems by using stable ACPI device name with a "i2c-"/"spi-" prefix for I2C/SPI slave device names. Both patches are independent from each other and can go through their own subsystems.
