The device goes away anyhow and the devm cleanups are called. As jsa1212_power_off() already emits an error message on failure and the additional error message by the i2c core doesn't add any useful information, change the return value to zero to suppress this message. This patch is a preparation for making i2c remove callbacks return void.
