These patches add support for a boot-time switch to enable PNP debug
messages. Currently, users have to recompile with CONFIG_PNP_DEBUG=y
to get PNP debug messages.
I copied the implementation strategy from Greg KH's USB patches:
http://lkml.org/lkml/2008/8/8/529
These patches don't fix any bugs, and I know it's pretty late to
consider new stuff for 2.6.27. The only reason to even consider them
is that 2.6.27 includes a significant PNP rewrite, and if 2.6.27 ends
up in a distro kernel, it will be much easier to work on problems if
users can collect debug information without rebuilding the kernel.
Bjorn
This patch just fixes indentation of a couple debug messages.

There are only a few remaining uses of pnp_info(), so I just
converted them to printk and removed the pnp_err(), pnp_info(),
pnp_warn(), and pnp_dbg() wrappers.
I also removed a couple debug messages that don't seem useful any
more ("driver registered", "driver unregistered", "driver attached").

Use scnprintf() to build up a buffer of PNP IDs to print. This
makes the printk atomic and helps get rid of an #ifdef.
Also remove an "#ifdef DEBUG" from some debug functions. The
functions only produce debug output, so it's OK to run the
function and just have the output be dropped at the end.

This adds the core function pnp_dbg() and a new config option to
enable it.
The PNP core debugging messages can be enabled at boot-time with the
"pnp.debug" kernel parameter.

pnp_dbg() is equivalent to dev_dbg() except that we can turn it

have to build a new kernel image.

CONFIG_PNP_DEBUG is no longer used to turn on dev_dbg() in PNP,
since we have pnp_dbg() which can be enabled at boot-time, so
this patch removes the config option.
Note that pnp_dock_event() checks "#ifdef DEBUG". But there's
never been a clear path for enabling that via configgery. It
happened that CONFIG_PNP_DEBUG enabled it after 1bd17e63a068db6,
but that was accidental and only in 2.6.26.

I would have pushed them up because they look harmless enough,
but after Linus' recent rant on merging windows on linux-kernel I've
reconsidered. Will queue them for .28 in test.
