Subject: [PATCH 05/11] dynamic_debug: use pr_info instead of printk(KERN_INFO ..
pr_info was already in use here, update most others.
Use pr_fmt to uniformly add __func__ to all calls.
A few printks were left alone, where line was left un-terminated,
and subsequent printks appended to it. These need separate attention.
