That depends on how much churn you want to have in old drivers that
generally don't have any users because the hardware is ancient or
no longer manufactured.

I suggest not changing those.

But I believe a coccinelle script was written quite awhile ago
to convert pr_<level> to dev_<level> when a struct device * is
available.
