Gustavo A. R. Silva ed4ed4043a bpf: verifier: avoid fall-through warnings
In preparation to enabling -Wimplicit-fallthrough, this patch silences
the following warning:

kernel/bpf/verifier.c: In function ‘check_return_code’:
kernel/bpf/verifier.c:6106:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (env->prog->expected_attach_type == BPF_CGROUP_UDP4_RECVMSG ||
      ^
kernel/bpf/verifier.c:6109:2: note: here
  case BPF_PROG_TYPE_CGROUP_SKB:
  ^~~~

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

Notice that is much clearer to explicitly add breaks in each case
statement (that actually contains some code), rather than letting
the code to fall through.

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

README

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.
