Subject: [PATCH v3 16/18] iio: magnetometer: ak8974: Simplify with dev_err_probe()
Date:   Sat, 29 Aug 2020 08:47:24 +0200
Message-Id: <20200829064726.26268-16-krzk@kernel.org>
In-Reply-To: <20200829064726.26268-1-krzk@kernel.org>
References: <20200829064726.26268-1-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.
