#    Description:
#      This is the makefile for building the in-tree gadget driver as an
#      out-of-tree driver with the CONFIG_FSL_UTP define set. This
#      define is required for the Windows DFU tool to initiate shell
#      commands via the MSC gadget driver, but causes the driver's MSC
#      functionality to break and presents a security vulnerability if
#      used in production builds.
