In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warning:
net/rxrpc/local_object.c: In function ‘rxrpc_open_socket’:
net/rxrpc/local_object.c:175:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (ret < 0) {
^
net/rxrpc/local_object.c:184:2: note: here
case AF_INET:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Currently, GCC is expecting to find the fall-through annotations
at the very bottom of the case and on its own line. That's why
I had to add the annotation, although the intentional fall-through
is already mentioned in a few lines above.
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.
