Subject: [RFT 1/3] power: supply: ab8500: Cleanup probe in reverse order
Date:   Fri,  4 Oct 2019 17:07:36 +0200
Message-Id: <20191004150738.6542-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It is logical to cleanup in probe's error path in reverse order to
previous actions.  It also makes easier to add additional goto labels
within this error path.
