I'm OK with this as long as somebody fixes the
s/inconsitencies/inconsistencies/
above.  I assume you've scanned all of drivers/acpi/ for similar
issues so they can all be fixed at once.

This is up to Rafael, of course.

Sorry about that, I can resubmit if necessary.

Yes. I scanned drivers/acpi for trailing whitespaces after I noticed a
couple of them. I did not explicitly scan for other stuff like spaces
where there should be tabs, mostly because I haven't found a quick and
reliable solution for that. I only noticed an inconsistent indentation
when committing, so I fixed that too.

You could try:

$ git ls-files -- 'drivers/acpi/*.[ch]' | \
  xargs ./scripts/checkpatch.pl -f --fix-inplace --types=CODE_INDENT

Right now that produces:

Up to you.  I hardly looked at the output.

I'd generally prefer to use a single line comment like

/* AC Adapter Management */

but I don't know how often that dashed block is used in ACPI.

grep seems to show the texts are not correctly centered so it seems like
it was done by hand and not that some automation tool was used to create
those blocks.

Maybe a separate patch could be done to change those if desired.
But not by me.

As far as I know, acpi was once autogenerated from a common source tree
and whitespace changes were once frowned on, but maybe that's changed or
or perhaps that's only for files in drivers/acpi/acpica/.  I don't know.

If anyone has a problem with them.

The latter.

I'm hesitant to touch those, mostly as you said because they're
subjective (and I don't really see any big issues with them). Seems to
be the prevalent style in the drivers/acpi, although there are other
block-like separator comments at least in drivers/acpi/dock.c.

Yeah, any changes to drivers/acpi/acpica would have to go through their
repo.

I'll go over the checkpatch output later and prepare a v2 that doesn't
touch the comments, unless anyone has any issues with that.
