Only thing we need - for that is to store the drm_fb_helper pointer somewhere in - drm_device->mode_config. And then we could roll that out to all the - drivers. - - tinydrm_gem_cma_prime_import_sg_table should probably go into the cma helpers, as a _vmapped variant (since not every driver needs the vmap).
