If anyone has any objections, please let me know. ------------------ From: Simon Que commit fa5199648e273a5e3e80aca41c1eb53700438dc1 upstream. This is meant to remove a compiler warning. It should not make any functional change. payload_len should be initialized when it is passed to write_tag_64_packet() as a pointer. If that call fails, this function should return early, and payload_len won't be used.
