Subject: [PATCH 06/10] power: supply: axp288_fuel_gauge: Store struct device pointer in axp288_fg_info
Date: Sat, 17 Jul 2021 18:44:20 +0200	[thread overview]
Message-ID: <20210717164424.274283-7-hdegoede@redhat.com> (raw)
In-Reply-To: <20210717164424.274283-1-hdegoede@redhat.com>

Directly store the struct device pointer in axp288_fg_info, rather then
storing a pointer to the struct platform_device there and then using
"&info->pdev->dev" everywhere.
