If you move to static inline for edac_device_handle_{ce,ue} the
symbols vanish and this breaks the abi. That's why the split in two
patches.

Your comment to not have a __ version as a third variant of the
interface makes sense to me. But to keep ABI your patch still needs to
be split. The first patch still must contain symbols for
edac_device_handle_{ce,ue}. I am not sure if ABI compatability is
something we want to make easier here. I personally like the approach.
