Subject: [PATCH 2/2] serial: core: Simplify with dev_err_probe()
Date:   Tue,  1 Sep 2020 17:31:00 +0200
Message-Id: <20200901153100.18827-2-krzk@kernel.org>
In-Reply-To: <20200901153100.18827-1-krzk@kernel.org>
References: <20200901153100.18827-1-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 the error value gets printed.
