[PATCH for v5.9] i2c: Replace HTTP links with HTTPS ones

[PATCH for v5.9] i2c: Replace HTTP links with HTTPS ones

[Alexander A. Klimov]

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

 (Actually letting a shell for loop submit all this stuff for me.)

 If there are any URLs to be removed completely
 or at least not (just) HTTPSified:
 Just clearly say so and I'll *undo my change*.

 If there are any valid, but yet not changed URLs:

 If you apply the patch, please let me know.

 Sorry again to all maintainers who complained about subject lines.
 Now I realized that you want an actually perfect prefixes,
 not just subsystem ones.
 I tried my best...
 And yes, *I could* (at least half-)automate it.
 Impossible is nothing! :)

The diffstat above does not match the changes below (specifically
i2c-piix4.rst is NOT modified by your actual patch).

A quick visit to this website shows that it is dead and useless. The
closest thing nowadays would be https://www.ali.com.tw/ however as far
as I know ALI sold their x86 chipset business to Nvidia in 2006. I
couldn't find information about these old chipsets on either website
though, so I believe that the best course of action would be to strip
the links and surrounding sentences.

I understand this is beyond the scope of your current project. Do you
want me to take care of that?

Yes, I've chosen "the easy way" of git commit --amend:
Editing the patch file.
I this a problem?

I don't agree with you.
IMAO broken links should be archive.org-ed.
I've added that to my todo list.

Usually, yes. It can easily create inconsitencies which make me as a
maintainer suspicious.
