I've just sent a patch which fixes this build failure with mx27_defconfig.
When CONFIG_BACKLIGHT_CLASS_DEVICE is not selected, the driver is now as 
it was before my patch.

I'll try to put the backligh things in a driver into backlight directory 
when I find time, which will remove the #ifdef

Also, I confirm the patch you sent for 
arch/arm/plat-mxc/include/mach/gpio.h is necessary to compile a kernel 
using mx27_defconfig .

Thanks,
Eric
