Subject: [PATCH 11/16] iio: chemical: scd30: Simplify with dev_err_probe()
Date:   Wed, 26 Aug 2020 16:51:48 +0200
Message-Id: <20200826145153.10444-11-krzk@kernel.org>
In-Reply-To: <20200826145153.10444-1-krzk@kernel.org>
References: <20200826145153.10444-1-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.
