/// Remove casting the values returned by memory allocation functions /// like kmalloc, kzalloc, kmem_cache_alloc, kmem_cache_zalloc etc. /// //# This makes an effort to find cases of casting of values returned by //# kmalloc, kzalloc, kcalloc, kmem_cache_alloc, kmem_cache_zalloc, //# kmem_cache_alloc_node, kmalloc_node and kzalloc_node and removes //# the casting as it is not required.
