Ji-Ze Hong (Peter Hong) 07a708f0a1 serial: 8250_fintek: Fix crash with baud rate B0
The 8250_fintek.c is support the Fintek F81866/F81216 with dynamic clock.
But It'll generate "division by zero" exception and crash in
fintek_8250_set_termios() with baud rate 0 on baudrate_table[i] % baud.

It can be tested with following C code:

	...
	struct termios options;

	tcgetattr(fd, &options);
	...
	options.c_cflag = CS8 | CREAD; /* baud rate 0 */
	tcsetattr(fd, TCSANOW, &options);
	tcflush(fd, TCIOFLUSH);

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
