[PATCH] iio: adc: at91-adc: Use devm_platform_ioremap_resource

From: Aishwarya R
Date: Sun Apr 12 2020 - 09:57:09 EST


From: Aishwarya Ramakrishnan <aishwaryarj100@xxxxxxxxx>

Use the helper function that wraps the calls to
platform_get_resource() and devm_ioremap_resource()
together. It reduces boilerplate and suggested by coccinelle.
