There is no need to initialize the dump data with zeros. data is allocated with vzalloc, so it's already zero-filled. More importantly, the memset is harmful, because dump->len (the length requested by userspace) can be bigger than the allocated buffer (whose size is determined by asking the driver's .get_dump_flag method).
