Details

Summary

jedec_ts(4) uses a sysctl format specifier of "IK4", to indicate that it
reports milliKelvin. However, sysctl(8) on stable/10 only knows about "IK",
without a numeric suffix, which represents deciKelvin.

Adjust the format specifier, and round the temperature value reported.

Test Plan

Load jedec_ts(4) on stable/10; note that the temperature reported is reasonable.

Would (temp + 500) / 1000 work just well here?

Yes, of course. That was the exact one-liner idiom I was thinking of, but couldn't remember at the time.

Use the obvious one-liner, which somehow escaped me at the time of the
original diff. Thanks, avg@!

LGTM.
Please fix the whitespace issue.

Thanks! Seems like indentation of this line is incorrect now (spaces vs tabs).
