This tells me what version the host is running. I frequently ask customers if
they are running on Host version X or Y. This tells me that with certainty
what they are running. The number of times I got from a customer that
they are running X while I knew that would not be possible has been pretty
high.

The new patch will have these removed. When I checked other drivers
in the drivers subdirectory the __func__ is used 15455 times most
of these are in print, debug or error lines. The __func__ in this
case only shows up if an error occurs.
But as requested, I will remove them.

They where compile and run tested. And syslog was not a mess. What did
I mess up here? The amount of printouts now are a fraction of what they
where before.
