| Subject: pinctrl: equilibrium: Fix device node reference leak in |
| pinbank_init() |
| |
| From: Felix Gu <ustc.gu@gmail.com> |
| |
| [ Upstream commit c0b4a4feeb43305a754893d8d9c6b2b5a52d45ac ] |
| |
| When calling of_parse_phandle_with_fixed_args(), the caller is |
| responsible to call of_node_put() to release the reference of device |
| node. |
| |
| In pinbank_init(), the reference of the node obtained from the |
| "gpio-ranges" property is never released, resulting in a reference |
| count leak. |
| |
| Add the missing of_node_put() call to fix the leak. |
| |
| Fixes: 1948d5c51dba ("pinctrl: Add pinmux & GPIO controller driver for a new SoC") |
