[PATCH 0/3] ARM: hisi: fix of_iomap errors

[Nicholas Mc Guire]

This patch set addresses two issues in arch/arm/mach-hisi/hotplug.c

1) The hisi hotplug functions were using a few unchecked 
   of_iomap() while at the same time the system relied on
   those mappings. Checks for !NULL were inserted.

2) Further some mandatory of_node_put() were missing and have
   been inserted.
