[ Upstream commit 3c89c70634bb0b6f48512de873e7a45c7e1fbaa5 ]
The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage.
Detected by coccinelle with the following warnings: ./drivers/pinctrl/pinctrl-rockchip.c:3221:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3196, but without a corresponding object release within this function. ./drivers/pinctrl/pinctrl-rockchip.c:3223:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3196, but without a corresponding object release within this function.
