It's not just for debugging, it works around the issue for devices that are
affected but not (yet) on the quirks list. So users of such devices can add it
to their kernel commandline so they can use the device - like all those i8042
parameters or "acpi.prefer_microsoft_dsm_guid" in the past.
I think this is more userfriendly (and a way familiar to many users) than
having them write an init script (or systemd unit or whatever) that writes some
debugfs option on boot?

> So both a DMI_PRODUCT_NAME + DMI_PRODUCT_FAMILY match?

After looking at
https://download.lenovo.com/consumer/mobiles_pub/ideapad_slim_3_hmm.pdf more
closely, it seems like *ABR8 and 82X* are not that closely related, it lists
several 82X* "machine types" that are not *ABR8, e.g. "IdeaPad Slim 3 14IAN8 1"
(82XA) or "IdeaPad Slim 3 16IRU8" (82X8).

From downloading a BIOS-update for my machine I know that the same BIOS is used
for several (probably all) Slim 3 *ABR8 devices, so it seems like this part of
the product family is the best way to match those devices:

OTOH that BIOS is also for the "IdeaPad Slim 5 Light 14ABR8" (82XS; note it's
"Slim 5" this time) (-:

Hooray for consistency!

IDK, I'll try to find out if it's feasible to match each device individually
after all, if I can find all the DMI_PRODUCT_FAMILY values of the devices using
either the same BIOS as mine or as Sindre's.

(I fear in the end it'll turn out that at least all Zen3 and Zen3+ IdeaPads are
affected anyway, but who knows - while many people have complained about this
bug online in the last years, a lot of them have only specified "IdeaPad Slim
3", and I don't think there's a good way to DMI-match the CPU generations
anyway)
