If anyone has any objections, please let me know. ------------------ From: Haoxiang Li commit e842f9a1edf306bf36fe2a4d847a0b0d458770de upstream. The return value of rio_add_net() should be checked. If it fails, put_device() should be called to free the memory and give up the reference initialized in rio_add_net().
