[PATCH 4/9] iommu/dma: Use helper functions to access dev->iommu_fwspec

From: Joerg Roedel
Date: Tue Dec 04 2018 - 11:30:43 EST


From: Joerg Roedel <jroedel@xxxxxxx>

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.
