Randy Dunlap afa751e84c kernel-doc: handle a void function without producing a warning
Currently a void function can produce a warning:
  main.c:469: warning: contents before sections

This one is from arch/x86/kernel/cpu/sgx/main.c (which is not included
in any produced kernel documentation output).

Handle this by setting $in_doc_sect to 1 whenever any recognized
document section name is processed.

Fixes: f624adef3d ("kernel-doc: limit the "section header:" detection to a select few")

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.
