Yesterday I ran a yum update on my fedora 21 running on a lenovo Carbon X1. Since then it seems my integrated webcam. Here is what I've gathered on my system so far :

The update did this :

Since then it seems cheese can't see the cam :

[ludo@Oulanl ~]$ cheese
** Message: cheese-application.vala:211: Error during camera setup: No device found
It seems the kernel is seeing the device (from journalctl) :

Are there any devices listed in Cheese's settings?

Nope it's empty. I now believe my webcam to be dead.

Maybe the easiest thing to check is to run a LiveUSB, since that should have (whatever broke) much closer to what you had before the upgrade?
