Subject: [PATCH v3 12/15] iommu/omap: Clean up bus_set_iommu()
Date: Tue,  5 Jul 2022 18:08:35 +0100	[thread overview]
Message-ID: <c1fbe2592488d98247ca7db2bbd9fe7115f01c98.1657034828.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1657034827.git.robin.murphy@arm.com>

Stop calling bus_set_iommu() since it's now unnecessary, and simplify
the init failure path accordingly.
