[PATCH 6.6 735/737] tty: fix tty_port_tty_*hangup() kernel-doc

[Greg Kroah-Hartman]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Slaby (SUSE) <jirislaby@kernel.org>

commit 6241b49540a65a6d5274fa938fd3eb4cbfe2e076 upstream.

The commit below added a new helper, but omitted to move (and add) the
corressponding kernel-doc. Do it now.

Fixes: 2b5eac0f8c6e ("tty: introduce and use tty_port_tty_vhangup() helper")
