Subject: [PATCH v2] crypto: talitos - Use devm_platform_ioremap_resource()
Date:   Thu,  6 Jun 2019 14:28:45 -0300
Message-Id: <20190606172845.16864-1-festevam@gmail.com>
Sender: linux-crypto-owner@vger.kernel.org
Precedence: bulk

Use devm_platform_ioremap_resource() to simplify the code a bit.

While at it, remove unneeded error message in case of
devm_platform_ioremap_resource() failure, as the core mm code
will take care of it.
