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"
