Subject: [PATCH] iio: adc: at91-adc: Use devm_platform_ioremap_resource
Date:   Sun, 12 Apr 2020 19:26:42 +0530
Message-Id: <20200412135644.4027-1-aishwaryarj100@gmail.com>
In-Reply-To: <20200409151125.32677-1-aishwaryarj100@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Aishwarya Ramakrishnan <aishwaryarj100@gmail.com>

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