Bug#1114557: [regression] 1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY") causes issue with ID 4c4a:4155 Jieli Technology USB Composite Device

[Staffan Melin <staffan.melin@oscillator.se>]

Ah, thanks, I get it now :)

So I got 6.16.7, and the patch applied without problems.

But no luck, the same results as before: touchscreen not working, xinput 
--list not showing the Jieli touchscreen. dmesg shows the same as 
before, too.

Best regards,

Staffan
