    treewide: Constify most dma_map_ops structures · 5299709d
    Bart Van Assche authored
    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/' \
           -e '/^static void vmd_setup_dma_ops/,/^}$/ s/const \(struct dma_map_ops \*dest\)/\1/' \
           -e 's/const \(struct dma_map_ops \*dest = \&vmd->dma_ops\)/\1/' \
        drivers/pci/host/*.c
    sed -i -e '/^void __init pci_iommu_alloc(void)$/,/^}$/ s/dma_ops->/intel_dma_ops./' arch/ia64/kernel/pci-dma.c
    sed -i -e 's/static const struct dma_map_ops sn_dma_ops/static struct dma_map_ops sn_dma_ops/' arch/ia64/sn/pci/pci_dma.c
    sed -i -e 's/(const struct dma_map_ops \*)//' drivers/misc/mic/bus/vop_bus.c
