[PATCH 4.9 03/27] tipc: fix memory leak in tipc_accept_from_sock()

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
