Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return or break from the middle of the loop, there is no put, thus causing a memory leak. Hence, for function cpsw_probe_dt, create an extra label err_node_put that puts the last used node and returns ret; modify the return statements in the loop to save the return value in ret and goto this new label. For function cpsw_remove_dt, add an of_node_put before the break. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: David S.
