[PATCH] staging: iio: ad9951: Use devm_iio_device_register

From: Himangi Saraogi
Date: Sun Aug 03 2014 - 06:00:55 EST


This patch introduces the use of devm_iio_device_register and does away
with the unregister in the remove function. The remove function is no
longer required and is completely removed.
