![]() [ Upstream commit c64e9710f9241e38a1c761ed1c1a30854784da66 ] ucmd in hns_roce_create_qp_common() are not initialized. But it works fine until new member sdb_addr is added to struct hns_roce_ib_create_qp. If the user-mode driver uses an old version ABI, then the value of the new member will be undefined after ib_copy_from_udata(). This patch fixes it by initialize this variable to 0. And the default value of the new member sdb_addr will be 0 which is invalid.
