Hi,

So as promised I've given this patch a try, unfortunately it breaks
existing users of ACPI serdev device instantation.

I've only had a short look at it so far. As far as I can tell, there are
two options: Either the device does not match/is being skipped, or there
are errors (which are currently only reported with dev_dbg, based on the
pre-patch implementation) causing the search to terminate early. I'll
keep investigating this and report back once I've got a better
understanding of the possible sources for this.

I haven't looked why your patch is breakig things, I have a large backlog
so I do not have time for that.

No worries, I'll try to figure this out.

But if you can provide me with a version of the patch with a bunch of
debug printk-s added I'm happy to run that for you.

Thank you for this offer, I will probably come back to it once I have
more of an idea what could cause the breakage.

Regards,

Maximilian
