Please use mm/memblock: or just memblock: prefix for memblock patches.
Besides, this patch does not fix a real error, it's only style fixup, so
"Fix ERROR" should be omitted here.

Again, this is not a real error in the code but rather a coding style
inconsistency. Please update the changelog text to reflect this.
