Dmitry Safonov 4086e2872f tty: Simplify tty->count math in tty_reopen()
commit cf62a1a13749db0d32b5cdd800ea91a4087319de upstream.

As notted by Jiri, tty_ldisc_reinit() shouldn't rely on tty counter.
Simplify math by increasing the counter after reinit success.

several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
