Subject: [PATCH 07/11] iio: dac ad8801: drop driver remove function

Remove driver remove callback in the ad8801 driver.

By making use of devm_iio_device_register(), we no longer need a driver
remove callback. Also since this was the last user of spi_get_drvdata(),
we can drop the call to spi_set_drvdata().
