you already have a struct device, so this is just odd. use dev_dbg()
instead and let it worry about dev_name() stuff. plus you're already
using dev_dbg() in the rest of the code, so i guess you just forgot
about this.

dont really need those braces

helper macro for this ?

shouldnt this be above the config_n

dont need the explicit .owner ?

itimer -> hrtimer ?
