Subject: [PATCH v2 3/4] crypto: stm32-hash - Simplify with dev_err_probe()
Date:   Thu, 10 Sep 2020 21:29:18 +0200
Message-Id: <20200910192919.12503-3-krzk@kernel.org>
In-Reply-To: <20200910192919.12503-1-krzk@kernel.org>
References: <20200910192919.12503-1-krzk@kernel.org>
Sender: linux-crypto-owner@vger.kernel.org
Precedence: bulk

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and the error value gets printed.
