usb: typec: fix unreleased fwnode_handle in typec_port_register_altmodes() 2024-11-08T15:30:53+00:00 Javier Carrasco javier.carrasco.cruz@gmail.com 2024-10-21T20:45:29+00:00 966cab9c2ec5a39324d0df059fc6a2214518d66f commit 9581acb91eaf5bbe70086bbb6fca808220d358ba upstream. The 'altmodes_node' fwnode_handle is never released after it is no longer required, which leaks the resource. Add the required call to fwnode_handle_put() when 'altmodes_node' is no longer required.
