You're right that there is a bug but this is not the right fix. The ade7854_i2c_write_reg_32() function returns 6 on success which makes no sense. It should be zero or negative error codes. All the write_reg functions in drivers/staging/iio/meter/ade7854-i2c.c have the same bug. Please, fix that instead and leave ade7854_initial_setup() alone. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
