> The drm_prime_pages_to_sg() function takes unsigned int argument to store
> length of the page vector, and the type of struct drm_gem_object::size is
> a size_t. The size of the object in CPU pages can not be negative, hence,
> use unsigned variable to store the number of pages, instead of the signed
> type.
