Can't you fit that printk in the switch(devid) block?  That wouldn't
require additional logic.  In fact, if you make the selected pin
configurable I wouldn't consider a printk explaining the current
policy/config assumptions necessary because that way there aren't any
policy-related assumptions made in the driver anymore.
