[PATCH v6 00/16] Fix several bad kernel-doc markups

[Mauro Carvalho Chehab]

Hi Jon,

This series have three parts:

1)  10 remaining fixup patches from the series I sent back on Dec, 1st:

   parport: fix a kernel-doc markup
   rapidio: fix kernel-doc a markup
   fs: fix kernel-doc markups
   pstore/zone: fix a kernel-doc markup
   firmware: stratix10-svc: fix kernel-doc markups
   connector: fix a kernel-doc markup
   lib/crc7: fix a kernel-doc markup
   memblock: fix kernel-doc markups
   w1: fix a kernel-doc markup
   selftests: kselftest_harness.h: partially fix kernel-doc markups

2) The patch adding the new check to ensure that the kernel-doc
   markup will be used for the right declaration;

3) 5 additional patches, produced against next-20210114 with new
   problems detected after the original series: 

 net: tip: fix a couple kernel-doc markups
 net: cfg80211: fix a kerneldoc markup
 reset: core: fix a kernel-doc markup
 drm: drm_crc: fix a kernel-doc markup
 platform/surface: aggregator: fix a kernel-doc markup

It probably makes sense to merge at least the first 11 patches
via the doc tree, as they should apply cleanly there, and
having the last 5 patches merged via each maintainer's tree.

-

Kernel-doc has always be limited to a probably bad documented
rule:

The kernel-doc markups should appear *imediatelly before* the
function or data structure that it documents.

On other words, if a C file would contain something like this:

	/**
	 * foo - function foo
	 * @args: foo args
	 */
	static inline void bar(int args);

	/**
	 * bar - function bar
	 * @args: foo args
	 */
	static inline void foo(void *args);


The output (in ReST format) will be:

	.. c:function:: void bar (int args)

	   function foo

	**Parameters**

	``int args``
	  foo args


	.. c:function:: void foo (void *args)

	   function bar

	**Parameters**

	``void *args``
	  foo args

Which is clearly a wrong result.  Before this changeset, 
not even a warning is produced on such cases.

As placing such markups just before the documented
data is a common practice, on most cases this is fine.

However, as patches touch things, identifiers may be
renamed, and people may forget to update the kernel-doc
markups to follow such changes.

This has been happening for quite a while, as there are
lots of files with kernel-doc problems.

This series address those issues and add a file at the
end that will enforce that the identifier will match the
kernel-doc markup, avoiding this problem from
keep happening as time goes by.

This series is based on current upstream tree.

@maintainers: feel free to pick the patches and
apply them directly on your trees, as all patches on 
this series are independent from the other ones.

v6:
  - rebased on the top of next-20210114 and added a few extra fixes

v5:
  - The completion.h patch was replaced by another one which drops
    an obsolete macro;
  - Some typos got fixed and review tags got added;
  - Dropped patches that were already merged at linux-next.

v4:

  - Patches got rebased and got some acks.
