It's normal the code is not present for the moment :-)

Juste put some number in /sys/module/pwc/parameters/trace
Like this:

   echo 65535 > /sys/module/pwc/parameters/trace

But, i see that the line is print using Info(), and does not depend of trace
level. So if you don't see it, perhaps it's another bit magic we need to
find.
