watchdog: rti_wdt: Fix an OF node leak in rti_wdt_probe()
[ Upstream commit 143981aa63f33d469a55a55fd9fb81cd90109672 ]
rti_wdt_probe() does not release the OF node reference obtained by
of_parse_phandle(). Add a of_node_put() call.
This was found by an experimental verification tool that I am
developing. Due to the lack of the actual device, no runtime test was
able to be performed.
