From 1bc6f83813441d15a74dfa97966fb68fa1bdec76 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 2 Jul 2009 18:32:05 +0200 Subject: [PATCH] amd-iommu: set evt_buf_size correctly The setting of this variable got lost during the suspend/resume implementation. But keeping this variable zero causes a divide-by-zero error in the interrupt handler. This patch fixes this.
