With dual core handling introduction, we now need to take care to always release lock before exiting function. Rework gpio_stm32_config to take this into account. Additionally, since ENOSYS usage is resevred to system calls handling, replace with EIO. Signed-off-by: Erwan Gouriou <[email protected]>
