[PATCH] drm/plane: Remove const qualifier from plane->modifiers allocation type

[PATCH] drm/plane: Remove const qualifier from plane->modifiers allocation type

[Kees Cook]

In preparation for making the kmalloc family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)

The assigned type is "uint64_t *", but the returned type, while matching,
will be const qualified. As there is no general way to remove const
qualifiers, adjust the allocation type to match the assignment.
