From dc82673f0cb5175dcec87041441cdb107932cd07 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 31 Oct 2017 13:28:16 +0000 Subject: sctp: fix error return code in sctp_send_add_streams() Fix to returnerror code -ENOMEM from the sctp_make_strreset_addstrm() error handling case instead of 0. 'retval' can be overwritten to 0 after call sctp_stream_alloc_out().
