commit34625c1931upstream. In the "gb_tty_set_termios" function the "newline" variable is declared but not initialized. So the "flow_control" member is not initialized and the OR / AND operations with itself results in an undefined value in this member. The purpose of the code is to set the flow control type, so remove the OR / AND self operator and set the value directly.

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.
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
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
