Subject: tipc: fix memory leak in tipc_accept_from_sock()
From: Jon Maloy <jon.maloy@xxxxxxxxxxxx>
[ Upstream commit a7d5f107b4978e08eeab599ee7449af34d034053 ]
When the function tipc_accept_from_sock() fails to create an instance of
struct tipc_subscriber it omits to free the already created instance of
struct tipc_conn instance before it returns.
We fix that with this commit.
