So -fno-builtin-stpcpy is not ideal solution then.. gcc may implement this opt
too and here we go again, red builds.
We should either provide stpcpy implementation or fix few places and do not use
sprintf there.

For some time the market wants medical grade accuracy in medical range,
while still retaining the declared accuracy outside of the medical range
within the same sensor. That is why we created extended calibration
which is automatically switched to when object temperature is too high.

There is some inconsistency and whitespace cleanup performed in this
patch. It was done on top of my other patches, but I can rebase to head
of the togreg branch if it would go in sooner.

If the specified/hinted sink is not reachable from a subset of the CPUs,

By default, coccicheck utilizes all available threads to implement
parallelisation. However, when all available threads are used,
a decrease in performance is noted. The elapsed time is minimum
when at most one thread per core is used.
For example, on benchmarking the semantic patch kfree.cocci
