Bjorn Helgaas 97ef062bbe PNP: add CONFIG_PNP_DEBUG_MESSAGES and pnp_dbg()
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.

---help---
Plug and Play (PnP) is a standard for peripherals which allows those
peripherals to be configured by software, e.g. assign IRQ's or other
parameters. No jumpers on the cards are needed, instead the values
are provided to the cards from the BIOS, from the operating system,
or using a user-space utility.
Say Y here if you would like Linux to configure your Plug and Play
devices. You should then also say Y to all of the protocols below.
Alternatively, you can say N here and configure your PnP devices
using user space utilities such as the isapnptools package.
If unsure, say Y.
config PNP_DEBUG_MESSAGES
default y
bool "PNP debugging messages"
depends on PNP
help
Say Y here if you want the PNP layer to be able to produce debugging
messages if needed. The messages can be enabled at boot-time with
the pnp.debug kernel parameter.
This option allows you to save a bit of space if you do not want
the messages to even be built into the kernel.
If you have any doubts about this, say Y here.
if PNP
config PNP_DEBUG
bool "PnP Debug Messages"
help
Say Y if you want the Plug and Play Layer to print debug messages.
This is useful if you are developing a PnP driver or troubleshooting.
