I can't help but think that this would be simpler to use if the
interface were something like acpi_set_modalias() and it did the
fallback to the ACPI HID internally.  It'd both avoid a small amount of
code duplication and make the code read a bit more naturally - I have to
think to realise that this means "if there isn't an OF name use the
HID" since it looks like a boolean function.  Then again just putting a
!= 0 in the test would have the same effect probably.
