[PATCH] hwmon: ina3221.c: 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. Hence add an of_node_put before the
return.
Issue found with Coccinelle.
