The current linux-next tree has a new error:

./Documentation/gpu/drm-mm:445: ./drivers/gpu/drm/drm_prime.c:994: WARNING: Error in declarator or parameters
Invalid C declaration: Expecting "(" in parameters. [error at 17]
  int __deprecated drm_prime_sg_to_page_array (struct sg_table *sgt, struct page **pages, int max_entries)
  -----------------^

While we might consider that documenting a deprecated interface is not
necessarily best practice, removing the error is easy.
