[CentOS] conflicts in updating to CR repo

Note, first of all I haven't actually updated, I'm just running "yum update"
to see what conflicts, if any, I get so I can be prepared when the final
7.7 release happens.

I've traditionally used the nvidia packages from elrepo, but recently
enabled rpmfusion (back when I started using 7.x, I disabled rpmfusion
because it took them a looooong time to get a EL7 repository up).

I use the priority plugin in yum, and have elrepo at priority 50
and rpmfusion at priority 60, so the elrepo nvidia packages
should "win", but yum seems to be confused about which packages
to use.

So now when doing yum update (with CR enabled) I get this long list
of dependency issues regarding the nvidia packages. I don't see any
reason to switch to the rpmfusion packages, elrepo seems to do a good
job of packaging and keeping them up to date:

 You could try using --skip-broken to work around the problem
 

Thanks in advance for advice!
