Subject: [PATCH 07/13] iommu/exynos: Clean up bus_set_iommu()
Date: Thu, 14 Apr 2022 13:42:36 +0100 [thread overview]
Message-ID: <0ae494b89a0fe9e233d067892caf33938571f599.1649935679.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1649935679.git.robin.murphy@arm.com>
Stop calling bus_set_iommu() since it's now unnecessary, and simplify
the init failure path accordingly.
