Subject: usb: dwc3: gadget: modify the scale in vbus_draw callback
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8a5b5c3c1634f9d7a96ea3b38f3d75333c887bf6;p=linux.git

usb: dwc3: gadget: modify the scale in vbus_draw callback

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.
