From 927d8f272e4f2ff20acbf3d4c21119b0e9d17cc2 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 1 Aug 2022 19:47:58 +0300 Subject: [PATCH] iommu: 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 dev_fwnode() API for that.
