Just as a heads up, git-send-email doesn't seem to pick up these To:
lines, so I had to dig this out of an archive.

This does seem to work for me, allowing various clk drivers to be used
as modules! This removes the functional need for my recent driver core
patch series around the deferred_probe_timeout (though the cleanup
bits in there may still be worth while).

Thanks for sending it out!

You mean 5.7-rc1, right?
