Thanks for the less fragile version!

Initially, a year ago or so, I tried to come up with a caching
mechanism for device caps, but that turned out to be even more
horrendous if I remember correctly (I no longer have the code). Like
not knowing when/if to invalidate entries etc. So I decided to attempt
that simple (previously) 4 line change.
