From ec58cbed3f8879ae9d9447f49ff3cd57f315f5d8 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 28 Apr 2017 13:09:23 +0100 Subject: atomisp: handle allocation calls before init in the hmm layer Currently the code handles this in the abstraction above. We want to remove that abstraction so begin by pushing down the sanity check. Unfortunately at this point we can't simply fix the init order.
