Subject: [PATCH 07/15] power: supply: cpcap-charger: Drop internal state and use generic stats
Date: Sun, 10 Jan 2021 21:53:55 +0200	[thread overview]
Message-ID: <20210110195403.13758-8-tony@atomide.com> (raw)
In-Reply-To: <20210110195403.13758-1-tony@atomide.com>

We currently have both state and status, get rid of state and use
generic status instead.
