this are not like the others. I think replacing the special-purpose
pciehp_debug with the generic dynamic debug thing is a good thing, but
I'd do it in a separate patch, e.g.,
- if (pciehp_debug)
- printk(KERN_DEBUG ...);
+ pr_dbg(...);
And that patch should also remove the pciehp_debug module parameter
and documentation at the same time, of course.
And the commit log should include an example of how to turn on these
messages, boot with "dyndbg='...'". I don't know what the magic
string there needs to be, so it'd be nice to have it in the commit log
and in a comment near the dbg() and ctrl_dbg() definitions.

Can these go in pciehp.h?
