When GPIOLIB is disabled, the build issue don't happen.What? It surely does happen!hmm.... Sure. you need to check the include/linux/gpio/consumer.h. Because of build error happen, you miss to include the "linux/gpio/consumer.h" header file in extcon-max3355.c. Please test it for enough time.
Yes, with this file #include'd, it build fine now.
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.Don't necessary. I already updated it including the "include/linux/gpio/consumer.h".
I saw that, yes.
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.This driver have to depend on GPIOLIB. Why are you disagreeing the COMPILE_TEST dependency? It is just compile test without anything.
I agree now. I still disagree about the gpiolib dependency though. MBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
