Subject: [PATCH 5/5] powerpc-MSI-HSTA: Move three assignments in
 hsta_msi_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 29 Aug 2016 11:30:48 +0200

Move the assignments for three data structure members to the end
so that they will only be performed if the desired resource allocations
succeeded by this function.
