Yes. As I explained earlier to some people there are facts affecting this:
- the function is operate on top of solely ACPI structures
- there is already similar function for GPIO and it stays like that

On top of this recently I've discovered, that i2c.h has separate #ifdef for I2C
and ACPI which theoretically might produce a linker error in some cases.
