Subject[PATCH] pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe
Date
This node pointer is returned by of_parse_phandle() with refcount
incremented in this function. Calling of_node_put() to avoid
the refcount leak.

Fixes: 32e67eee670e ("pinctrl: nomadik: Allow prcm_base to be extracted from Device Tree")
