An IOMMU driver that allocated a vIOMMU may want to revert the allocation, if it encounters an internal error after the allocation. So, there needs a destroy helper for drivers to use.
A brief explanation or a small code snippet illustrating a typical allocation and potential abort scenario would be helpful.
Move iommufd_object_abort() to the driver.c file and the public header, to introduce common iommufd_struct_destroy() helper that will abort all kinds of driver structures, not confined to iommufd_viommu but also the new ones being added in the future.
