When we compile pinctrl layer for platforms without CONFIG_PINCONF, we get following compilation errors: drivers/built-in.o: In function `pinctrl_show': linux-2.6/drivers/pinctrl/core.c:1116: undefined reference to `pinconf_show_setting' drivers/built-in.o: In function `pinctrl_maps_show': linux-2.6/drivers/pinctrl/core.c:1071: undefined reference to `pinconf_show_map' drivers/built-in.o: In function `pinctrl_init_device_debugfs': linux-2.6/drivers/pinctrl/core.c:1224: undefined reference to `pinconf_init_device_debugfs' make[1]: *** [.tmp_vmlinux1] Error 1 This patch fixes this.
