I would rather not delete these comments because they are very old and
I believe were debugging lines in the past. I hope we will never have
to dig into this driver anymore but if we have to, I would suggest to
use debug printk's instead.

Also, if you want to clean up a bit the driver, you can go a little bit
further and address eg. all whitespace issues.
