On current linus/HEAD, m68k allmodconfig gives:

drivers/gpio/devres.c:52: error: redefinition of âdevm_gpio_requestâ
include/linux/gpio.h:99: error: previous definition of
âdevm_gpio_requestâ was here

make[5]: *** [drivers/gpio/devres.o] Error 1

The !CONFIG_GENERIC_GPIO dummy definitions in include/linux/gpio.h conflict
with the real ones in drivers/gpio/devres.c.
Should devres.c really be compiled if !CONFIG_GENERIC_GPIO?

In 3.7, this doesn't show up as CONFIG_GPIOLIB is not enabled. I assume
it gets selected by some driver.
