From 18c807dbf9d6dabd624b2f4dcf5c668a42567c15 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Mon, 12 Nov 2018 18:52:36 +0800 Subject: [PATCH] power: supply: sc2731_charger: Add charger status detection The USB charger status can be notified before the charger driver registers the USB phy notifier, so we should check the charger status in probe() in case we missed the USB charger notification.
