I removed the printk(s) from tune_fan(); the ones leaved replaced
both the ones inside tune_fan() and the ones outside.
Anyway, Benjamin which is your opinion ?
For me is equal to remove or to leave "(tune +0)" (when the tuning is equal to
0).
Jean think it is better to remove "(tune +0)" (when the tuning is equal to 0).
So if you haven't any objection I will remove it.
