Subject: [PATCH 2/7] power: supply: cpcap-battery: Fix low battery check
Date: Sun,  7 Apr 2019 11:12:49 -0700	[thread overview]
Message-ID: <20190407181254.64537-3-tony@atomide.com> (raw)
In-Reply-To: <20190407181254.64537-1-tony@atomide.com>

We need to check current instead of the charge counter to see if
a charger is connected. The charge counter shows the cumulated value
instead of the current charge current and can be negative or positive.
