[PATCH] PNP: export pnp_bus_type
The PNP framework doesn't export "pnp_bus_type", which is an unfortunate
exception to the policy followed by pretty much every other bus. I noticed
this when I had to find a device in order to provide its platform_data.
Note that per advice from Arjan, the "export" scope has been been minimized to
avoid the hundred-plus bytes needed to support access from modules. In this
case, the symbol is only needed by statically linked kernel code that lives
outside the drivers/pnp directory.
