From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> From: Antonio Borneo <borneo.antonio@xxxxxxxxx> commit d5efc2e6b98fe661dbd8dd0d5d5bfb961728e57a upstream. With GCC 10, building usbip triggers error for multiple definition of 'udev_context', in: - libsrc/vhci_driver.c:18 and - libsrc/usbip_host_common.c:27. Declare as extern the definition in libsrc/usbip_host_common.c.
