Driver core fixes for 5.5-rc2

Browse Source 
Here are two small driver core fixes to resolve some reported issues
 
 The first is to handle the much-reported (by the build systems) problem
 that superH does not boot anymore.
 
 The second handles an issue in the new platform logic that a number of
 people ran into with the automated tests in kbuild
 
 Both of these have been in linux-next with no reported issues.
