Subject: [PATCH 4/9] iommu/dma: Use helper functions to access dev->iommu_fwspec
Date: Tue, 11 Dec 2018 13:19:05 +0100	[thread overview]
Message-ID: <20181211121910.5604-5-joro@8bytes.org> (raw)
In-Reply-To: <20181211121910.5604-1-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

Use the new helpers dev_iommu_fwspec_get()/set() to access
the dev->iommu_fwspec pointer. This makes it easier to move
that pointer later into another struct.
