[Spice-devel] [PATCH v8 06/20] usb-backend: add safe check on attach()

[Victor Toso]

From: Frediano Ziglio <fziglio at redhat.com>

At this moment, spice_usb_backend_channel_attach() is only related to
real devices and this call might happen on channel-up event that can
possibly come before usbredirhost has been created.
