(Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct dmz_mblock **" but the returned type will be "struct dmz_mblk **". These are the same allocation size (pointer size), but the types do not match. Adjust the allocation type to match the assignment.
