This one fails to build here: linux/drivers/gpio/gpiolib.c: In function 'export_store': linux/drivers/gpio/gpiolib.c:625:18: error: 'EPROBE_DEFER' undeclared (first use in this function) linux/drivers/gpio/gpiolib.c:625:18: note: each undeclared identifier is reported only once for each function it appears in There is no EPROBE_DEFER functionality on 3.2 and in gpio_request, so I think the patch can be safely dropped.
