dma_buf_ops are not supposed to change at runtime. All functions
working with dma_buf_ops provided by <linux/dma-buf.h> work with
const dma_buf_ops. So mark the non-const structs as const.
File size before:
text data bss dec hex filename
1240 112 0 1352 548 drivers/gpu/drm/omapdrm/omap_gem_dmabuf.o
File size After adding 'const':
text data bss dec hex filename
1352 0 0 1352 548 drivers/gpu/drm/omapdrm/omap_gem_dmabuf.o

Thanks! I've picked this and the 3 other constifying patches to omapdrm
tree.
