From: Yoshihiro Shimoda <[email protected]>

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.

Fixes cf06df3fae28 ("usb: gadget: udc: renesas_usb3: move pm_runtime_{en,dis}able()")
