I think this resolves the aux device probe/remove issue via a common bus. But it
does not help with the mdev device needing a lot of the device handling calls
from the parent driver as it share the same handling as the parent device. My
plan is to export all the needed call via EXPORT_SYMBOL_NS() so the calls can be
shared in its own namespace between the modules. Do you have any objection with
that?
