6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Hattori <joe@xxxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 0508316be63bb735f59bdc8fe4527cadb62210ca ]
netxbig_leds_get_of_pdata() does not release the OF node obtained by
of_parse_phandle() when of_find_device_by_node() fails. Add an
of_node_put() call to fix the leak.
This bug was found by an experimental static analysis tool that I am
developing.
