Subject[PATCH v6 1/6] iommu/tegra-smmu: Rename struct iommu_group *group to *grp
Date
There are a few structs using "group" for their pointer instances.
This gets confusing sometimes. The instance of struct iommu_group
is used in local function with an alias "grp", which can separate
it from others.

So this patch simply renames "group" to "grp" as a cleanup.
