SubjectRe: [RFC PATCH 22/57] drivers: i2c: Use generic helper to match device by acpi_dev

> - dev = bus_find_device(&i2c_bus_type, NULL, adev,
> - i2c_acpi_find_match_device);
> + dev = bus_find_device(&i2c_bus_type, NULL, adev, device_match_acpi_dev);

In general, this looks like a nice cleanup which I am in favour of.
However, I didn't understand why ACPI uses bus_find_device() but OF has
a seperate helper bus_find_device_by_of_node(). Why this inconsistency
of having a seperate helper here and not there?
