From edcde848c01eb071a91d479a6b3101d9cf48e905 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 28 May 2024 13:25:03 +0300 Subject: [PATCH] PNP: Hide pnp_bus_type from the non-PNP code The pnp_bus_type is defined only when CONFIG_PNP=y, while being not guarded by ifdeffery in the header. Moreover, it's not used outside of the PNP code. Move it to the internal header to make sure no-one will try to (ab)use it.
