Hi,

This small series fixes two probe-time error handling issues in the
virtio-iommu driver.

The first patch avoids dereferencing a device after dropping the
reference returned by bus_find_device(). The second patch propagates
failures from iommu_device_register() and unwinds the resources that
were set up earlier in probe.

Xiong Weimin (2):
iommu/virtio: Avoid use-after-put in viommu_get_by_fwnode
iommu/virtio: Handle iommu_device_register() failures
