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> --- net/batman-adv/translation-table.c | 1 + 1 file changed, 1 insertion(+) Compile tested only.
