Subject: [PATCH 1/9] iommu/amd: Use BUS_NOTIFY_REMOVED_DEVICE
Date: Wed, 1 Apr 2015 14:58:44 +0200 [thread overview]
Message-ID: <1427893132-18310-2-git-send-email-joro@8bytes.org> (raw)
In-Reply-To: <1427893132-18310-1-git-send-email-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
Use the new device-notifier event instead of the old
BUS_NOTIFY_DEL_DEVICE to make sure the device driver had a
chance to uninit the device before all its mappings are
teared down.
