From d068c350c0486ba9011abb6f91cdc0c12b522155 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 2 Mar 2016 15:31:04 -0700 Subject: [PATCH] x86/PCI: VMD: Set bus resource start to 0 The bus always starts at 0. Due to alignment and down-casting, this happened to work before, but looked alarmingly incorrect in kernel logs.
