One thing that I've wanted to start doing for a while now is request
patch submissions like this to come accompanied with a way on how to
test them. Ideally this would be in a scripted way that can test for
success programatically, but it doesn't necessarily have to be if it
turns out too difficult or impractical to do.

The goal is to eventually come up with a test suite that can run the
majority of test cases automatically to make it easy to test for any
regressions. And even if tests can't be run automatically it'd still
be an advantage to have them all collected in some repository, since
it saves a lot of typing and time to run tests, and it will give us
a standard set of tests that everybody can verify changes against.

I realize that it's somewhat unfair to start requesting this from you
now, but we've got to start somewhere. Could you give a short summary
of how you test this? What are the interfaces that the kernel exposes
for these thermal drivers?
