i think it would be good to return with error if !allocator or !pnode
and remove the resulting duplicated DBC_REQUIRE.

can we add a check for !dev_obj and !dev_obj->proc_list just to be
sure that we get always the correct pointer?

can we check for !hdev_obj, !already_attached even if we have the
DBC_REQUIRE?, maybe we can actually remove the DBC_REQUIRE that could
be redundant after applying this.

The same comment as above.
