[Qemu-devel] [PATCH 2/4] Preparation for usb-bt-dongle conditional build

[Gerd Hoffmann]

From: Miroslav Rezanina <mrezanin@redhat.com>

To allow disable usb-bt-dongle device using CONFIG_BLUETOOTH option, some of
functions in vl.c file has to be made accessible in dev-bluetooth.c. This is
pure code moving.
