Well, I do not know about that, I always thought DTS was stupid anyway.
My patch is not changing the DTS logic, only the name of a variable to
reflect its usage in the current code and avoid conflict with the next
patch. The next patch is the important one.
If the DTS logic needs fixing and you (or anybody else) end up doing it,
then the name of the variable can be fixed at the same time. And having
"dts" in it will help finding it.
