Hi! Anybody to shed a light why we have two stubs of gpio_is_valid() and one actual declaration? % git grep -n -w gpio_is_valid -- include/ include/asm-generic/gpio.h:44:static inline bool gpio_is_valid(int number) include/asm-generic/gpio.h:143:static inline bool gpio_is_valid(int number) include/linux/gpio.h:109:static inline bool gpio_is_valid(int number) -- With Best Regards, Andy Shevchenko
