Commit0f3a8c3f34("iio: Add support for creating IIO devices via configfs") declared but never implemented iio_sw_device_type_configfs_{un}register(). Commitb662f809d4("iio: core: Introduce IIO software triggers") declared but never implemented iio_sw_trigger_type_configfs_{un}register(). Commita3e0b51884("iio: accel: add support for FXLS8962AF/FXLS8964AF accelerometers") declared but never implemented fxls8962af_core_remove(). Commit8dedcc3eee("iio: core: centralize ioctl() calls to the main chardev") declared but never implemented iio_device_ioctl(). Commitd430f3c36c("iio: imu: inv_mpu6050: Use regmap instead of i2c specific functions") removed inv_mpu6050_write_reg() but not its declaration.
