When trying to disable a key that is not supported by the device we should report error, not do nothing and report success: root@yocto:/sys/devices/soc0/gpio-keys# cat keys 114-116 root@yocto:/sys/devices/soc0/gpio-keys# echo 77 > keys root@yocto:/sys/devices/soc0/gpio-keys# We want 'echo 77 > keys' to report an error, but silence to give us an illusion that all is 'ok'.
