[Patch V2 2/2] iommu: remove sysfs_link to device in iommu_group/devices when failed

[Wei Yang]

The original code forgets to remove the sysfs_link to a device in
iommu_group/devices directory, when the creation fails or conflicts on the
name.

This patch tries to remove the sysfs_link on the failure.
