Subject: [PATCH 3.14 17/17] KVM: vgic: return int instead of bool when checking I/O ranges

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Will Deacon <will.deacon@....com>

commit 1fa451bcc67fa921a04c5fac8dbcde7844d54512 upstream.

vgic_ioaddr_overlap claims to return a bool, but in reality it returns
an int. Shut sparse up by fixing the type signature.
