From 1b6998c96ccc60a61bdb812b4a55866224ab9708 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sat, 29 Oct 2016 16:11:57 +0000 Subject: ACPI / gpio: add missing fwnode_handle_put() in acpi_gpiochip_scan_gpios() fwnode_handle_put() should be used when terminating device_for_each_child_node() iteration with break or return to prevent stale device node references from being left behind. This is detected by Coccinelle semantic patch.
