Subject: [PATCH] VMD: Set bus resource start to 0
Date: Mon, 22 Feb 2016 14:22:40 -0700 [thread overview]
Message-ID: <1456176160-9086-1-git-send-email-keith.busch@intel.com> (raw)
The bus always starts at 0. Due to alignment and down-casting, this
happened to work before, but looked alarmingly incorrect in kernel logs.
