Did you mean pr_cont() for both of these? Otherwise each one will get
a level + device info prefix.

This wants a device node, not a driver name string. There's a reason
there was no , in the old macro...

Does that compile? What was wrong with the old way again?

Isn't the first argument for dev_* supposed to be a device? This
should probably be

dev_info(dev, KBUILD_MODNAME ": " s, ##args

just like the old macro had. You're passing the module name as the
device pointer, which should trigger nasty warnings.

[Stopping review here. Please make sure everything compiles and
doesn't introduce horrible-looking warnings]
