From 77e110936a42b212c0fb576356ed274eb1d90c54 Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Mon, 22 Jan 2024 12:03:49 +0100 Subject: tty: vt: make types around consw::con_blank() bool Both the mode_switch parameter and the return value (a redraw needed) are true/false. So switch them to bool, so that users won't return -Eerrors or anything else. And document the hook. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.
