From 2184a60de26b94bc5a88de3e5a960ef9ff54ba5a Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Mon, 29 Jul 2013 20:46:04 -0700 Subject: [PATCH] KVM: ARM: Squash len warning The 'len' variable was declared an unsigned and then checked for less than 0, which results in warnings on some compilers. Since len is assigned an int, make it an int.
