[PATCH v1 06/22] iio: adc: ltc2497: Get platform data via dev_get_platdata()

[Andy Shevchenko]

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

Access to platform data via dev_get_platdata() getter to make code cleaner.

While at it, drop duplicate NULL check that iio_map_array_register()
already has.
