From bc38ee10fc26338e21c01485540f815be1f3db28 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 21 Jul 2016 18:54:10 +0300 Subject: intel_iommu: avoid unnamed fields Also avoid unnamed fields for portability. Also, rename VTD_IRTE to VTD_IR_TableEntry for coding style compliance. Signed-off-by: Michael S.
