batman-adv: Fix mem leak in the batadv_tt_local_event() function
Memory is allocated for 'tt_change_node' with kmalloc(). 'tt_change_node' may go out of scope really being used for anything (except have a few members initialized) if we hit the 'del:' label. This patch makes sure we free the memory in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Acked-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: David S. Miller <davem@davemloft.net>
