Subject: [PATCH 06/12] PNP: use correct format characters

From: Bill Wendling <isanbard@...il.com>

When compiling with -Wformat, clang emits the following warnings:

drivers/pnp/interface.c:273:22: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
                pnp_printf(buffer, pnp_resource_type_name(res));
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Use a string literal for the format string.
