6.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kuniyuki Iwashima <kuniyu@xxxxxxxxxx> [ Upstream commit e263691773cd67d7c824eeee8b802f50c6e0c118 ] __mptcp_init_sock() always returns 0 because mptcp_init_sock() used to return the value directly. But after commit 18b683bff89d ("mptcp: queue data for mptcp level retransmission"), __mptcp_init_sock() need not return value anymore. Let's remove the unnecessary test for __mptcp_init_sock() and make it return void.
