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

Hi Zhang, hi Jiri,

In Debian Staffan Melin reported that after an update containing the
commit 1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY"),
the input device with same idVendor and idProduct, the Jieli
Technology USB Composite Device, does not get recognized anymore.

The full Debian report is at: https://bugs.debian.org/1114557

The issue is not specific to the 6.12.y series and confirmed in 6.16.3
as well.

Staffan Melin did bisect the kernels between 6.12.38 (which was still
working) and 6.1.41 (which was not), confirming by bisection that the
offending commit is 

1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY")

#regzbot introduced: 1a8953f4f774
#regzbot monitor: https://bugs.debian.org/1114557

So it looks that the quirk applied is unfortunately affecting
negatively as well Staffan Melin case.

Can you have a look?

Regards,
Salvatore
