Hi and thank you for your quick feedback!

Yes, I've tested the kernel in unstable, 6.16, and it didn't recognize 
the touchscreen.

Now, in the stable repos I also found 6.12.41, which doesn't recognize 
the touchscreen either, so that leaves us with a smaller number of 
commits. Great!

I compiled 6.12.38, and the problem is not there.

Next I compiled 6.12.41 and the problem is there.

On to bisect. After the last bisect I got:

716a0c8dedc63700cf1480906faf8d9e2687bfae is the first bad commit

     HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY

     [ Upstream commit 1a8953f4f7746c6a515989774fe03047c522c613 ]

     MARTLINKTECHNOLOGY is a microphone device, when the HID interface in 
an
     audio device is requested to get specific report id, the following 
error
     may occur.

     Ignore HID interface. The device is working properly.

It looks like the device mentioned in the last commit and my touchscreen 
device has the same manufacturer id, 4C4A, so maybe this quirk is 
affecting the touchscreen too?

Best regards,

Staffan

Thanks a lot, this looks you have identified a way to move forward. I
just have forwarded your report with your findings upstream and kept
you and the bugreport in the loop.

https://lore.kernel.org/regressions/aL2gYJaXoB6p_oyM@eldamar.lan/T/#u

Let's see how we can handle that.

Regards,
Salvatore
