Subject: [PATCH AUTOSEL 6.6 09/14] usb: typec: use cleanup facility for 'altmodes_node'

From: Javier Carrasco <javier.carrasco.cruz@...il.com>

[ Upstream commit 1ab0b9ae587373f9f800b6fda01b8faf02b3530b ]

Use the __free() macro for 'altmodes_node' to automatically release the
node when it goes out of scope, removing the need for explicit calls to
fwnode_handle_put().
