treewide: Constify most dma_map_ops structures
Most dma_map_ops structures are never modified. Constify these
structures such that these can be write-protected. This patch
has been generated as follows:
git grep -l 'struct dma_map_ops' |
xargs -d\\n sed -i \
-e 's/struct dma_map_ops/const struct dma_map_ops/g' \
-e 's/const struct dma_map_ops {/struct dma_map_ops {/g' \
-e 's/^const struct dma_map_ops;$/struct dma_map_ops;/' \
-e 's/const const struct dma_map_ops /const struct dma_map_ops /g';
sed -i -e 's/const \(struct dma_map_ops intel_dma_ops\)/\1/' \
$(git grep -l 'struct dma_map_ops intel_dma_ops');
sed -i -e 's/const \(struct dma_map_ops dma_iommu_ops\)/\1/' \
$(git grep -l 'struct dma_map_ops' | grep ^arch/powerpc);
sed -i -e '/^struct vmd_dev {$/,/^};$/ s/const \(struct dma_map_ops[[:blank:]]dma_ops;\)/\1/' \
