Subject: iommu/virtio: Reverse arguments to list_add
Git-commit: fb3637a113349f53830f7d6ca45891b7192cd28f
Patch-mainline: v5.7-rc5
References: bsc#1172068
Elsewhere in the file, there is a list_for_each_entry with
&vdev->resv_regions as the second argument, suggesting that
&vdev->resv_regions is the list head. So exchange the
arguments on the list_add call to put the list head in the
second argument.
Fixes: 2a5a31487445 ("iommu/virtio: Add probe request")
