Subject: [PATCH v3 02/15] ACPI/IORT: Remove direct access of dev->iommu_fwspec
Date: Fri, 20 Mar 2020 10:14:01 +0100 [thread overview]
Message-ID: <20200320091414.3941-3-joro@8bytes.org> (raw)
In-Reply-To: <20200320091414.3941-1-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
Use the accessor functions instead of directly dereferencing
dev->iommu_fwspec.
