From 2b5eac0f8c6e79bc152c8804f9f88d16717013ab Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Wed, 11 Jun 2025 12:02:47 +0200 Subject: tty: introduce and use tty_port_tty_vhangup() helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This code (tty_get -> vhangup -> tty_put) is repeated on few places. Introduce a helper similar to tty_port_tty_hangup() (asynchronous) to handle even vhangup (synchronous). And use it on those places. In fact, reuse the tty_port_tty_hangup()'s code and call tty_vhangup() depending on a new bool parameter.
