iommu/dma: Use helper functions to access dev->iommu_fwspec

joergroedel · joergroedel · commit 98cc4f719642 · 2018-12-17T10:38:30.000+01:00
Use the new helpers dev_iommu_fwspec_get()/set() to access
the dev-&gt;iommu_fwspec pointer. This makes it easier to move
that pointer later into another struct.
