Subject: [PATCH v3 25/34] iommu/rockchip: Convert to probe/release_device() call-backs
Date: Wed, 29 Apr 2020 15:37:03 +0200 [thread overview]
Message-ID: <20200429133712.31431-26-joro@8bytes.org> (raw)
In-Reply-To: <20200429133712.31431-1-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
Convert the Rockchip IOMMU driver to use the probe_device() and
release_device() call-backs of iommu_ops, so that the iommu core code
does the group and sysfs setup.
