Hi Stefan,

You are correct.  I did read them all and check instances of device, so
I'm not sure how I misread this file.  Did you have a specific build
that triggered a failure, or you just happened to spot it?  I'm guessing
that it gets device.h by another path and hence won't show up in build
coverage.

If so I'll definitely get it fixed, but I might wait a day or two to see
if anything else pops up, if it isn't explicitly causing any breakage.

Thanks for the report,
Paul.
