Why? Where is the error here?

Also:

"Both American and British English spellings are allowed within the
kernel documentation.  There is no need to fix one by replacing it with
the other."

Also looking at git log, plenty of _s_ spellings.

Thanks. As you might be aware this was tested with acpm-based tmu
and with dvfs/cpufreq both on e850-96. They are local changes here but I
can't send all of them in one go -- I need dependencies first.
