Merge tag 'tty-5.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty fix from Greg KH: "Here is a single tty kgdb fix for 5.3-rc4. It fixes an annoying log message that has caused kdb to become useless. It's another fallout from commit ddde3c18b700 ("vt: More locking checks") which tries to enforce locking checks more strictly in the tty layer, unfortunatly when kdb is stopped, there's no need for locks :) This patch has been linux-next for a while with no reported issues" * tag 'tty-5.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: kgdboc: disable the console lock when in kgdb
