Description:
I ended up having two device files for my internal webcam on my Thinkpad X200 with this kernel. No other video hardware installed, only the build-in webcam. Additional info: $uname -a Linux localhost.localdomain 4.17.12-arch1-1-ARCH #1 SMP PREEMPT Fri Aug 3 07:16:41 UTC 2018 x86_64 GNU/Linux $ls -l /dev/video* crw-rw----+ 1 root video 81, 0 7.
