From 739e2425fea6349ac674e93648953b3a08985f2f Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 25 Mar 2014 10:47:05 +1100 Subject: [PATCH] KVM: PPC: Book3S HV: Return ENODEV error rather than EIO If an attempt is made to load the kvm-hv module on a machine which doesn't have hypervisor mode available, return an ENODEV error, which is the conventional thing to return to indicate that this module is not applicable to the hardware of the current machine, rather than EIO, which causes a warning to be printed.
