Subject: [PATCH 4/5] hv: Reverse order of resources in hyperv_mmio
Date: Wed, 24 Feb 2016 21:24:01 +0000	[thread overview]
Message-ID: <1456349042-16275-5-git-send-email-jakeo@microsoft.com> (raw)
In-Reply-To: <1456349042-16275-1-git-send-email-jakeo@microsoft.com>

From: Jake Oshins <jakeo@microsoft.com>

A patch later in this series allocates child nodes
in this resource tree.  For that to work, this tree
needs to be sorted in ascending order.
