Subject: [PATCH] counter/ftm-quaddec: Use device-managed registration API
Date:   Thu, 25 Jul 2019 16:54:58 +0800
Message-Id: <20190725085458.21838-1-hslester96@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make use of devm_counter_register.
Then we can remove redundant unregistration API
usage to make code simpler.
