From b8423a2f5814dbf055ed7c41f25bfe91c2066cbe Mon Sep 17 00:00:00 2001 From: Javier Carrasco Date: Sun, 20 Oct 2024 14:56:35 +0200 Subject: usb: typec: qcom-pmic-typec: fix missing fwnode removal in error path If drm_dp_hpd_bridge_register() fails, the probe function returns without removing the fwnode via fwnode_handle_put(), leaking the resource. Jump to fwnode_remove if drm_dp_hpd_bridge_register() fails to remove the fwnode acquired with device_get_named_child_node().
