Gustavo A. R. Silva 0843bdc14c watchdog: machzwd: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warnings:

drivers/watchdog/machzwd.c: In function ‘zf_set_timer’:
./arch/x86/include/asm/io.h:355:14: warning: this statement may fall through [-Wimplicit-fallthrough=]
 #define outw outw
drivers/watchdog/machzwd.c:80:53: note: in expansion of macro ‘outw’
 #define zf_writew(port, data)  { outb(port, INDEX); outw(data, DATA_W); }
                                                     ^~~~
drivers/watchdog/machzwd.c:179:3: note: in expansion of macro ‘zf_writew’
   zf_writew(COUNTER_1, new);
   ^~~~~~~~~
drivers/watchdog/machzwd.c:180:2: note: here
  case WD2:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

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.
