Subject: usb: gadget: udc: renesas_usb3: fix oops in renesas_usb3_remove()
From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
commit e3190868e5f52fb26544f16463593d54ce46ce61 upstream.
This patch fixes an issue that the renesas_usb3_remove() causes
NULL pointer dereference because the usb3_to_dev() macro will use
the gadget instance and it will be deleted before.
