And no, it shouldn't depend on gpiolib. It has empty stubs for the case of CONFIG_GPIOLIB=n. Obviously something is wrong with the GPIO headers, I'll look into it.Yes. When GPIOLIB is disabled, the build issue don't happen.
What? It surely does happen!
because include/linux/gpio/consumer.h implement the dummy function for all gpio functions if CONFIG_GPIOLIB is disabled.
Linus W. advised to #include this header explicitly -- I'll try and post.
For correct operation of max3355, you should add the dependency to the extcon-max3355.c driver. This driver use the GPIO library certainly.
I disagree. The driver will just cease to load in this case. I don't see why we need such dependency. Only compilation time dependencies should be
specified, I think.
COMPILE_TEST is used for just build test. You can see the detailed data[1]. [1] https://lkml.org/lkml/2013/5/22/155
I know. Re-read my question please.
