Care to provide a "real" changelog comment for this patch? We need
something here.

Why is this in a .c file? externs should never be in a .c file.

Why? Who really cares? And, if you _really_ want to do this, please
use a dev_dbg() call instead, which ties it properly into the dynamic
printk system _and_ properly identifies this deivce.

You never enabled anything, yet you said you did? Somethings wrong
here.

Same for this printk, you didn't stop anything.
Also fix it up and don't use printk, see above.
