Yes, I don't see any urgent reason to push this hack in. Better to check
dev_name change first. What I'm going to propose there is "spix.y" to

We probably need to be able to match on ACPI name alone as some BIOS
settings can change the I2C bus number and break the name match used at
bind time. e.g. on Haswell the codec can either be on I2C bus 0 or 7.
Indeed. The way I initially read the suggestion above the idea was to
replace the bus number with the ACPI name for the device which seemed
sensible but now I reread the bus number is still there.
Sorry, my textual proposal above was confusing and should have used
different variables for ACPI name. What I meant was "spix.y" ->
"spi-INTABCD:ij" and "x-00yz" to "i2c-INTABCD:ij" where "INTABCD:ij" was
the ACPI device name which contains the device instance in "ij".
