Uninstall v4l-dvb

I was trying to get my webcam to work, but no success. In the process, I installed this: v4l-dvb. Now, my webcam is not found anymore (but it’s listed in hardware).

I want to uninstall that thing, but I’m not getting it. I tried “make uninstall”, but it doesn’t work.

Can someone help me with this, please?

Thank you!
