So how does this work? If I build for-next I get: drivers/gpio/gpiolib-cdev.c: In function ‘gpio_v2_line_config_validate’: drivers/gpio/gpiolib-cdev.c:1334:14: error: implicit declaration of function ‘mem_is_zero’; did you mean ‘xa_is_zero’? [-Werror=implicit-function-declaration] 1334 | if (!mem_is_zero(lc->padding, sizeof(lc->padding))) | ^~~~~~~~~~~ | xa_is_zero Cheers, Kent.
