[merged] kernel-resource-make-iomem_resource-implicit-in-release_mem_region_adjustable.patch removed from -mm tree

[akpm]

The patch titled
     Subject: kernel/resource: make iomem_resource implicit in release_mem_region_adjustable()
has been removed from the -mm tree.  Its filename was
     kernel-resource-make-iomem_resource-implicit-in-release_mem_region_adjustable.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: David Hildenbrand <david@redhat.com>
Subject: kernel/resource: make iomem_resource implicit in release_mem_region_adjustable()

"mem" in the name already indicates the root, similar to
release_mem_region() and devm_request_mem_region().  Make it implicit. 
The only single caller always passes iomem_resource, other parents are not
applicable.
