[PATCH] crypto: nx: nx-842-powernv: Add of_node_put() before return

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
