Hi Rob,
Here devtype is initialised.

And in the old code devtype was conditionally re-initialised here, if a match with data was found.
But in the new code devtype is re-initialised unconditionally.
Possibly I am missing something obvious, but it seems that either this should somehow be made conditional, or the initialisation to &xcan_axi_data should be dropped.
