From 0c9ccaf24efa5b8f728445272ebc84754da2a512 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 1 Aug 2022 19:51:42 +0300 Subject: [PATCH] iommu/virtio: Do not dereference fwnode in struct device In order to make the underneath API easier to change in the future, prevent users from dereferencing fwnode from struct device. Instead, use the specific device_match_fwnode() API for that.
