With my previous patch this now causes build failures like: drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt': drivers/nfc/s3fwrn5/uart.c:100:14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration] These did not show up in my randconfig tests because randconfig almost always has GPIOLIB selected by some other driver, and I did most of the testing with follow-up patches that address the failures properly. Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment to avoid the build failures. It can be moved back and turned off by default once all the driver specific changes are merged.
