In case cma_init_reserved_mem failed, need to free the memblock allocated by memblock_reserve or memblock_alloc_range. Quote Catalin's comments: https://lkml.org/lkml/2019/2/26/482 Kmemleak is supposed to work with the memblock_{alloc,free} pair and it ignores the memblock_reserve() as a memblock_alloc() implementation detail. It is, however, tolerant to memblock_free() being called on a sub-range or just a different range from a previous memblock_alloc(). So the original patch looks fine to me.
