This is the way Joe suggested, how to use printk's:
You define the pr_fmt(fmt) before any includes and you can just do 
'pr_notice("Fan control off, to enable:\n");' to printk a notice which looks 
like this: "acerhdf: Fan control off...". Same with pr_err(...) which prints 
an error.

kind regards,
