Subject: [PATCH 1/2] usb: dwc3: gadget: modify the scale in vbus_draw callback
Date: Sun, 28 Mar 2021 02:28:08 +0800 [thread overview]
Message-ID: <20210327182809.1814480-2-raychi@google.com> (raw)
In-Reply-To: <20210327182809.1814480-1-raychi@google.com>
Currently, vbus_draw callback used wrong scale for power_supply.
The unit of power supply should be uA.
Therefore, this patch will fix this problem.
Fixes: 99288de36020 ("usb: dwc3: add an alternate path in vbus_draw callback")
