hwmon: Fix resource leaks for device_node

[PATCH 0/2] hwmon: Fix resource leaks for device_node

Posted by Felix Gu 3 weeks, 3 days ago

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In current code, it does not release the reference, causing a resource leak.

I wonder why these commits did not get the tag “Fixes”
together with the “stable” annotation.
