iommu/io-pgtable: Rename iommu_gather_ops to iommu_flush_ops
In preparation for TLB flush gathering in the IOMMU API, rename the iommu_gather_ops structure in io-pgtable to iommu_flush_ops, which better describes its purpose and avoids the potential for confusion between different levels of the API. $ find linux/ -type f -name '*.[ch]' | xargs sed -i 's/gather_ops/flush_ops/g' Signed-off-by: Will Deacon <will@kernel.org>
