Subject: [PATCH 5/6] power: supply: sc27xx: Make sure the alarm capacity is larger than 0
Date: Wed, 31 Jul 2019 18:00:27 +0800	[thread overview]
Message-ID: <5c3bb516c6020410a932c12eb2481fd75c34b7fe.1564566425.git.baolin.wang@linaro.org> (raw)

In-Reply-To: <cover.1564566425.git.baolin.wang@linaro.org>

From: Yuanjiang Yu <yuanjiang.yu@unisoc.com>

We must make sure the alarm capacity is larger than 0, to help to
calibrate the low battery capacity.
