From cbcdc1debd02e1a2cbc1367ee7e0213e1041f738 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 10 Feb 2007 01:45:13 -0800 Subject: [PATCH] [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.
