Maybe dev_XXX() should report full sysfs path do the dveice? Still does
not help with the fact that "driver" shown for class devices is not so
interesting as it will always be the class name.

Well, the dev_printk logic could certainly have simple rules to avoid
duplicate information. And perhaps pick the most relevant parts using
some heuristics.

Right now it just prints out "%s %s" for dev_driver_string(dev) and
dev_name(dev) respectively. That really isn't all that wonderfully
beautiful, and results in things like

  hid-generic 0003:046D:C526.0006: xyz

for my Logitech USB Receiver. That's kind of ugly, and really doesn't
clarify anything at all, I think.

The "driver + dev_name()" works fine for things like PCI devices, but
even then it's partly because the PCI layer has made sure to make the
device name pretty - and the device name contains the (redundant) data
of which bus number it is on, even though that's strictly a matter of
the parent thing (but the device name has been prettified and contains
redundant information exactly so that it would print out nicely).
