Subject: [PATCH] vfio/iommufd: Return errno in iommufd_cdev_attach_ioas_hwpt()

In preparation to implement auto domains have the attach function
|
||
|
|
return the errno it got during domain attach instead of a bool.
|
||
|
|
|
||
|
|
-EINVAL is tracked to track domain incompatibilities, and decide whether
|
||
|
|
to create a new IOMMU domain.
