Patch applied.

Hm.

$ git grep of_mm_gpiochip_add
arch/powerpc/sysdev/cpm1.c:     return of_mm_gpiochip_add(np, mm_gc);
arch/powerpc/sysdev/cpm1.c:     return of_mm_gpiochip_add(np, mm_gc);
arch/powerpc/sysdev/cpm_common.c:       return of_mm_gpiochip_add(np, mm_gc);
arch/powerpc/sysdev/ppc4xx_gpio.c:              ret =
of_mm_gpiochip_add(np, mm_gc);
arch/powerpc/sysdev/qe_lib/gpio.c:              ret =
of_mm_gpiochip_add(np, mm_gc);
arch/powerpc/sysdev/simple_gpio.c:      ret = of_mm_gpiochip_add(np, mm_gc);
drivers/gpio/gpio-ge.c: return of_mm_gpiochip_add(pdev->dev.of_node, mmchip);
drivers/gpio/gpio-mm-lantiq.c:  ret =
of_mm_gpiochip_add(pdev->dev.of_node, &chip->mmchip);
drivers/gpio/gpio-mpc5200.c:    ret =

drivers/gpio/gpio-mpc5200.c:    ret =
of_mm_gpiochip_add(ofdev->dev.of_node, &chip->mmchip);
drivers/gpio/gpio-mpc8xxx.c:    ret = of_mm_gpiochip_add(np, mm_gc);
drivers/gpio/gpio-xilinx.c:     status = of_mm_gpiochip_add(np, &chip->mmchip);
drivers/gpio/gpio-zevio.c:      status =
of_mm_gpiochip_add(pdev->dev.of_node, &(controller->chip));

Should these all be patched to use this, or reviewed for applicability?
