GPIO_ETRAXFS is a bool symbol, so gpio-etraxfs.o can only be built-in,
right?

(A patch was submitted that would allow built-in only code to use
builtin_platform_driver(), see https://lkml.org/lkml/2015/5/10/125 .)

But the code this patch adds contains a bit of module specific
boilerplate. Was it perhaps your intention to make GPIO_ETRAXFS
tristate?
