X-Git-Tag: v4.1-rc1~70^2^3~8
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=6c5cc8015793cdfd56d9997bcfddf2740ff716c5;p=linux.git

iommu/amd: Use BUS_NOTIFY_REMOVED_DEVICE

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.
