Re: [PATCH 2/2] cxl/region: Fix missing put_device(region_dev)

Btw, I assume you're doing some kind of static analysis?  Looking for
missing NULL checks is very tricky and I haven't found a way to do it
well except for looking at failed allocations.  Allocations have to be
checked.

There are so many other functions where we leave off the NULL check
because the caller knows it can't fail.
