From 1c7d1bcad218808a4f67a4492a5e1d920e85c239 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Wed, 3 Sep 2008 16:58:35 -0700 Subject: [PATCH] dmar: fix dmar_parse_dev() devices_cnt error condition check It is possible that, instead of PCI endpoint/sub-hierarchy structures, only IO-APIC/HPET devices may be reported under device scope structures. Fix the devices_cnt error check, which cares about only PCI structures and removes the dma-remapping unit structure (dmaru) when the devices_cnt is zero and include_all flag is not set.
