Bug#1114557: [PATCH v2] HID: quirks: Add device descriptor for 4c4a:4155

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

Thank you Salvatore, for moving this forward.

I can add that the issue has been reported by several users on a GPD DUO 
channel on Discord -- all are on newer kernels but have different Linux 
distributions.

I can also confirm that the patch does solve my problem. Looking forward 
to some resolution of this, as it stops me from upgrading to Testing. :)

Best regards,

Staffan
