Subject: iommu/tegra: Use helper functions to access dev->iommu_fwspec
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=db5d6a70043a0073e59af99cd4fd6bcb5bd3ace2;p=linux.git

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

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.
