UpX regression during 7.0 merge window

[charleskeepax]

Commit bb6a3c2 "ASoC: SOF: Intel: hda: add SDCA property check" seems to cause some issues on my UpX. I get a lot of messages about duplicate sysfs entries:

[ 5.699086] kobject: kobject_add_internal failed for SDW0-Playback-SimpleJack with -EEXIST, don't try to register things with the same name in the same directory.

Looking back through the log I do see this:

[ 5.299442] rt711-sdca sdw:0:0:025d:0711:01: SDCA properties not found in BIOS

I think there is some interaction between that patch and the ghost Realtek codecs that live in older ACPIs. I assume it ends up creating DAI links for that device or something, but not had a chance to investigate fully yet. Will update more tomorrow.

OK right done a little more digging on this and I don't think this is a real issue. This only happens if you have function topology enabled and a ghost device in the ACPI. I think we see this because we are hacking things so function topologies are enabled on older platforms.

I think the only action here is just to double check are we sure that all systems for which function topology is enabled do not have ghost devices in the ACPI?
