Subject: [PATCH 3/3] mfd: wcd934x: Simplify with dev_err_probe()
Date:   Wed, 26 Aug 2020 16:49:35 +0200
Message-Id: <20200826144935.10067-3-krzk@kernel.org>
In-Reply-To: <20200826144935.10067-1-krzk@kernel.org>
References: <20200826144935.10067-1-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.
