so its seems that the function drm_prime_sg_to_page_addr_arrays its not defined ..and others

[temporary999]

Solution

Line 234 of the file fl2000_gem.c: $ nano +234 fl2000_gem.c Change: ret = drm_prime_sg_to_page_addr_arrays(sgt, obj->pages, NULL, obj->num_pages); To: ret = drm_prime_sg_to_page_array(sgt, obj->pages, obj->num_pages);
