Subject: [PATCH v1 1/1] PNP: Export pnp_bus_type for modules

Since we have dev_is_pnp() macro that utilises the address of pnp_bus_type
variable, the users, which can be compiled as modules, will be failed to
build. Export the variable to the modules to prevent build breakage.

Reported-by: Woody Suwalski <terraluna977@...il.com>
Closes: https://lore.kernel.org/r/cc8a93b2-2504-9754-e26c-5d5c3bd1265c@gmail.com
Fixes: 2a49b45cd0e7 ("PNP: Add dev_is_pnp() macro")
