Anti-pattern, fixing...

According to docs only driver can be 0 (NULL is invalid though)

We should 100% be warning users though, not blind returning from this function

I can add the warning yes. It's highly unlikely a user works of see it though this merely only happens when you for example check devito.version within a docker build (which won't show the warning )

Check out my changes and see if you agree

I thought there were use cases where you might run Devito on a login node without the driver before deploying on a compute node with the driver (in which case warning but not failing seems like a good course of action)

That's a use case too yes. As of your change I personally prefer the library call and value check in separate statements but that's really not important so can just merge.
FYI was breaking the pro editable install because it was failing to check version during building
