[PATCH v3 04/27] staging: iio: resolver: ad2s1210: check return of ad2s1210_initial()

[David Lechner <dlechner@baylibre.com>]

From: David Lechner <david@lechnology.com>

From: David Lechner <dlechner@baylibre.com>

This adds a check to the return value of ad2s1210_initial() since it
can fail. The call is also moved before devm_iio_device_register() so
that we don't have to unregister the device if it fails.
