Subject: kmsan: export kmsan_handle_urb
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 7ba594d700998bafa96a75360d2e060aa39156d2 upstream.
USB support can be in a loadable module, and this causes a link failure
with KMSAN:
ERROR: modpost: "kmsan_handle_urb" [drivers/usb/core/usbcore.ko] undefined!
Export the symbol so it can be used by this module.
