Personally, I've never liked this, because the local headers could have
stuff that impacts global headers. And if there are conflicts, you kind
of want to have your local one look like the culprit (although modern
compilers are pretty good at showing both sites).

Note that to keep headers self-contained, this is not enough for headers
not associated with a .c, which is why we have the HDRTEST rule in i915.

Do you have the style file somewhere?

Nitpick, throughout the series, I would leave a blank line after the
SPDX and copyright boilerplate, regardless of whether it's an #include
or header guard #ifdef that follows. They're not comments about what
follows, which is what it feels like when they're directly attached to
something that follows without a blank line.

Here, having the .h corresponding to the .c just looks like it's not
properly sorted.
