- * @sgt: Scatter/gather table of pinned pages
- *
- * This function imports a scatter/gather table exported via DMA-BUF by
- * another driver using drm_gem_cma_prime_import_sg_table(). It sets the
- * kernel virtual address on the CMA object. Drivers should use this as their
- * &drm_driver->gem_prime_import_sg_table callback if they need the virtual
- * address. tinydrm_gem_cma_free_object() should be used in combination with
- * this function.
- *
- * Returns:
- * A pointer to a newly created GEM object or an ERR_PTR-encoded negative
- * error code on failure.
