This patch fixes following cleanup issues:
 - The return value of the function is
   inconsistent with the actual return type.
 - After the pointer type is directly converted
   to the '__le64' type, the program may crash
   or produce unexpected results.

Please explain why you're casting twice.

I'm sorry. I made a mistake here. unsigned long and uintptr_t are the 
same data type in linux kernel. The type cast is invalidly repeated 
here. Can I just keep (unsigned long) one cast?
