arch_pnpbios_disabled() is defined in architecture code on x86, but this does not include the appropriate header, causing a warning: arch/x86/kernel/platform-quirks.c:42:13: error: no previous prototype for 'arch_pnpbios_disabled' [-Werror=missing-prototypes] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Reviewed-by: Alexander Lobakin <aleksander.lobakin@intel.com> Link: https://lore.kernel.org/all/20230516193549.544673-10-arnd%40kernel.org
