mxser_stop_rx() should be called from mxser_shutdown_port() for several reasons: 1) info->slock is held while manipulating IER (as on other places), 2) hangup now stops rx too, 3) mxser_close() will use tty_port_close() and there is no place except tty_port_operations::shutdown() where this can be done, 4) this is the same sequence as serial_core does. So we can map this code 1:1 when switching the driver to it.

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.
