Subject[PATCH] kmsan: export kmsan_handle_urb
Date
From: Arnd Bergmann <arnd@arndb.de>

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.

Fixes: 553a80188a5d ("kmsan: handle memory sent to/from USB")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
