[Qemu-devel] [PATCH] spapr: pci: clean msi info when releasing it

From: Liu Ping Fan
Subject: [Qemu-devel] [PATCH] spapr: pci: clean msi info when releasing it
Date: Wed, 7 May 2014 14:51:11 +0800

In current code, we use phb->msi_table[ndev].nvec to indicate whether
this msi entries are used by a device or not. So when unplug a pci
device, we should reset nvec to zero.
