Subject: [PATCH v2 10/18] iio: amplifiers: hmc425a: Simplify with dev_err_probe()
Date:   Thu, 27 Aug 2020 21:26:34 +0200
Message-Id: <20200827192642.1725-10-krzk@kernel.org>
In-Reply-To: <20200827192642.1725-1-krzk@kernel.org>
References: <20200827192642.1725-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
