I'm now seeing this on another device too, but this time the error
thrown is -EBADE, this seems to be new with recent kernels:
Yup. Before we were passing firmware errors up to user-space, which was confusing and potentially be misinterpreted. However, looking at the output below it would have been good to log the firmware error as well. And staring at it some more I suddenly realize I broke the feature detection module with this change. Actually only the GSCAN feature detection.

It would be good if we can silence these errors, or maybe at a
minimum lower their log-level from error to warning?
I had a look at it and it seems to be a difference in firmware api that we need to support in the driver. Need to do a bit more digging, but it seems an actual issue. You could silence it for now, but I prefer to wait for the fix.
Ok, what is the ETA of a fix for this?
Regards,
Hans
