drivers/gpu/drm/amd/amdgpu/../display/dc/basics/logger.c:73:23-27: WARNING: casting value returned by memory allocation function to (char *) is useless. Remove casting the values returned by memory allocation functions like kmalloc, kzalloc, kmem_cache_alloc, kmem_cache_zalloc etc. Semantic patch information: 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. The result in the patch case may need some reformatting.
