Hi all,

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

drivers/tty/tty_port.c:400: warning: expecting prototype for tty_port_tty_hangup(). Prototype was for __tty_port_tty_hangup() instead

Introduced by commit

  2b5eac0f8c6e ("tty: introduce and use tty_port_tty_vhangup() helper")
