Subject: [PATCH 3/5] Input: s3c2410_ts: Use devm_platform_ioremap_resource()
Date:   Thu,  4 Apr 2019 12:47:21 +0530
Message-Id: <1554362243-2888-4-git-send-email-mojha@codeaurora.org>
In-Reply-To: <1554362243-2888-1-git-send-email-mojha@codeaurora.org>
References: <1554362243-2888-1-git-send-email-mojha@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

devm_platform_ioremap_resource() internally have platform_get_resource()
and devm_ioremap_resource() in it. So instead of calling them separately
use devm_platform_ioremap_resource() directly.
