In the end, don't we want to use netdev_dbg() everywhere where we work
with a struct net_device? And use dev_dbg() everywhere where we work
with a struct device (or a struct usb_interface)?
At least that's how I understand commit 8f26b8376faa ("checkpatch:
update suggested printk conversions") description:
Direct conversion of printk(KERN_<LEVEL>... to pr_<level> isn't the
preferred conversion when a struct net_device or struct device is
available.
Do you think it is worth going straight for netdev_dbg()/dev_dbg() to
avoid redoing it later?

If we're going to stay with pr_debug(), using KBUILD_MODNAME seems to be
the convention among drivers when defining pr_fmt():
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
