Subject: [PATCH v4 03/16] drm/msm/mdp5: Remove direct access of dev->iommu_fwspec
Date: Thu, 26 Mar 2020 16:08:28 +0100
Message-ID: <20200326150841.10083-4-joro@8bytes.org> (raw)
In-Reply-To: <20200326150841.10083-1-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

Use the accessor functions instead of directly dereferencing
dev->iommu_fwspec.
