Subject: [PATCH 1/2] gpio: aggregator: Drop pre-initialization in get_arg()
Date:   Tue, 23 Jun 2020 16:57:47 +0200
Message-Id: <20200623145748.28877-2-geert+renesas@glider.be>
In-Reply-To: <20200623145748.28877-1-geert+renesas@glider.be>
References: <20200623145748.28877-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In get_arg(), the variable start is pre-initialized, but overwritten
again in the first statement.  Rework the assignment to not rely on
pre-initialization, to make the code easier to read.
