I'd love to, I'm still reading up on how to build modules under Debian
A first attempt is attached, I'll send it standalone once I've tested it.

Thanks! I wouldn't have noticed that, the struct is inserted in vid:pid order

Subject: [PATCH 1/1] media: uvcvideo: Add quirk for Mini640 Thermal Camera
The thermal camera "2bdf:0102 HIK Camera" sold as a "Mini640"
long-wave infrared camera crashes Cheese and errors under gstreamer's
v4l2src missing both TRY_FMT and VIDIOC_S_FMT
Using the quirk UVC_QUIRK_PROBE_MINMAX yields a clean v4l2-compliance report
and allows streaming at all supported resolutions under gstreamer
