mxser_receive_chars_old() is used whenever MOXA_MUST_LSR_RERR is set in status no matter the HW ID (the last 'if'). So there is no need for another check of MOXA_MUST_LSR_RERR _with_ hwid == MOXA_MUST_MU860_HWID (the third 'if'). Hence remove this subcase. That allows us to check status on a single line with both UART_LSR_BRK_ERROR_BITS (from the second 'if') and MOXA_MUST_LSR_RERR (the last 'if').

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.
