Subject: [PATCH] sparc: i8042-sparcio.h: fix unused kbd_res warning

kbd_res is used only when CONFIG_PCI is defined; condition its declaration as
well. This fixes the following compilation warning:

  drivers/input/serio/i8042-sparcio.h:20:25: warning: ‘kbd_res’ defined but not used [-Wunused-variable]

Hi,

This can be seen with e.g. sparc alldefconfig.

Best regards,

V.
