Johan Hovold 0d3cb6f6c6 Revert "tty: fix NULL pointer issue when tty_port ops is not set"
This reverts commit f4e68d58cf.

TTY drivers using the tty-port abstraction all provide a pointer to a
set of port operations, which specifically cannot be NULL (or we'd find
out at first attempt to open a port).

Revert the recent commit which added unnecessary NULL-checks and whose
commit message indicated that it was fixing a real problem, which it did
not.

Note that even the two tty drivers for virtual devices currently
providing an empty set of operations probably should be implementing at
least some of the callbacks.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
