Hi all,

After merging the tty tree, today's linux-next build (htmldocs) produced
this warning:

drivers/tty/tty_io.c:2271: warning: cannot understand function prototype: 'bool tty_legacy_tiocsti __read_mostly = IS_ENABLED(CONFIG_LEGACY_TIOCSTI); '

Introduced by commit

  83efeeeb3d04 ("tty: Allow TIOCSTI to be disabled")
