Sometimes it is useful to examine the timing of kcontrol events.

Add debug statements to each kcontrol.

Thanks. I just put a #define DEBUG into the first line and rebuilt the
module. It will be faster this way :)

I will send a v2.

Since this doesn't always show up, I don't mind to have the function
name shown explicitly there.  OTOH, what bothers me is that all those
messages have a short format "__func__: %d" while the values are
utterly different, depending on the function.  That can be confusing.
IMO, it'd be more user-friendly to indicate what values are presented,
too.


thanks,

Takashi
