Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> --- drivers/crypto/nx/nx-842-powernv.c | 1 + 1 file changed, 1 insertion(+)
