I believe the current uses of pr_err in this module
are unnecessary or could be converted to pr_debug.

I think __func__/line aren't particularly useful.

I prefer log messages prefixed with the module name.

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

and I'd convert all the current pr_err to pr_debug
and convert the printk(KERN_ERR to pr_err(

cheers, Joe
