From c0b4a4feeb43305a754893d8d9c6b2b5a52d45ac Mon Sep 17 00:00:00 2001 From: Felix Gu Date: Tue, 27 Jan 2026 01:30:07 +0800 Subject: [PATCH] pinctrl: equilibrium: Fix device node reference leak in pinbank_init() 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.
