Nguyen Dinh Phi 6811744bd0 netrom: Decrease sock refcount when sock timers expire ... [ Upstream commit 517a16b1a88bdb6b530f48d5d153478b2552d9a8 ] Commit 63346650c1 ("netrom: switch to sock timer API") switched to use sock timer API. It replaces mod_timer() by sk_reset_timer(), and del_timer() by sk_stop_timer(). Function sk_reset_timer() will increase the refcount of sock if it is called on an inactive timer, hence, in case the timer expires, we need to decrease the refcount ourselves in the handler, otherwise, the sock refcount will be unbalanced and the sock will never be freed.
