From fb3637a113349f53830f7d6ca45891b7192cd28f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 5 May 2020 20:47:47 +0200 Subject: [PATCH] iommu/virtio: Reverse arguments to list_add 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.
