Subject: [PATCH/RFC v2 2/4] iommu/ipmmu-vmsa: Get rid of disabled device check
Date: Fri, 27 Jan 2017 15:14:25 +0900 [thread overview]
Message-ID: <148549766541.22203.15197831330522408915.sendpatchset@little-apple> (raw)
In-Reply-To: <148549764733.22203.16459470412085471955.sendpatchset@little-apple>
From: Magnus Damm <damm+renesas@opensource.se>
Since of_iommu_configure() now skips over disabled devices
we can simply drop this check in the IPMMU driver.
