From 7a467e02b339a50ed2762edd72e763925ac2b0a3 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 17 Jul 2023 15:12:14 -0300 Subject: iommufd/selftest: Return the real idev id from selftest mock_domain Now that we actually call iommufd_device_bind() we can return the idev_id from that function to userspace for use in other APIs.
