Some kernel-doc fixes

Hi Jon,

That's the second version of the kernel-doc fixup patch series.

I discovered the root cause why Sphinx logger was not working: there was a call there for logger.verbose(). According with:

https://www.sphinx-doc.org/en/master/extdev/logging.html

This is a valid call, but it doesn't verbose messages. Instead, it is crashing with modern Sphinx versions, causing the log to not work.

I got rid of it, replacing by logger.info(). I took the time to also address an issue pointed by Andy: not having the same log message placed everywhere. With such change, we can keep using Sphinx logger (which produces colored messages) inside kernel-doc classes.

With that, we have:

Patch 1: cleanup try/except logic and get rid of logger.verbose();
Patch 2: fix a KeyError when trying to acess data from non-existing files;
Patch 3: makes Lore and kernel-doc ML receive patches related
to kernel-doc.py and get_abi.py.

If you test just patch 1 on the top of next-20250516, you'll see the keyerror message (in red):

ERROR: Cannot find file ./drivers/gpio/gpiolib-acpi.c
ERROR: Cannot find file ./drivers/gpio/gpiolib-acpi.c
WARNING: kernel-doc './scripts/kernel-doc.py -rst -enable-lineno -export ./drivers/gpio/gpiolib-acpi.c' processing failed with: KeyError('./drivers/gpio/gpiolib-acpi.c')

And the script doesn't crash anymore. After patch 2, the try/except warning gets replaced by a proper message:

ERROR: Cannot find file ./drivers/gpio/gpiolib-acpi.c
ERROR: Cannot find file ./drivers/gpio/gpiolib-acpi.c
WARNING: No kernel-doc for file ./drivers/gpio/gpiolib-acpi.c

Please apply it to solve the issues that are reported by Stephen and Akira.

Regards,
Mauro

Changes to ABI and kernel-doc need to be c/c linux-doc. Update the maintainer's entry to cover those files.

Please ignore this... It got just the last patch... It reminds I didn't trink my usual cup of coffee this morning.

I opted to re-order the series placing the MAINTAINERS patch first, with the hope that Lore would pick the entire series as submissions for linux-doc.

Thanks,
Mauro
