Subject: [PATCH v3 00/56] Fix several bad kernel-doc markups

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.

Jon,

The first patch contains a trivial bug fix that I got
at kernel-doc script while writing this series. Feel
free to pick it anytime.

The last one should likely be applied only after we
have everything else in place, as otherwise it will 
produce hundreds of warnings, and the broken
markups will be ignored.
