The sun4i_ss_opti_poll function cipher data until the output miter have a length of 0. If the crypto API client, give more SGs than necessary this could result in an infinite loop. Fix it by checking for remaining bytes, just like sun4i_ss_cipher_poll(). Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com>
