Subject: [PATCH 5/6] gpio: pisosr: Simplify with dev_err_probe()
Date:   Thu, 27 Aug 2020 22:08:26 +0200
Message-Id: <20200827200827.26462-5-krzk@kernel.org>
In-Reply-To: <20200827200827.26462-1-krzk@kernel.org>
References: <20200827200827.26462-1-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.
