Hello Kirill,

The patch worked like a charm! See attached screenshot. :)

```

I also recompiled the kernel, just to be thorough, with
`UVIDEO_DEBUG` added, as you suggested. I attach the dmesg.boot with the
flag enabled for your reference, but as I said the webcam works with
the patch regardless.

Thank you so much for the quick response and for the patch. Hope this
makes it into -current! :)

Yours

requiem
