Subject: xen, fbfront: fix connecting to backend
From: Juergen Gross <jgross@suse.com>
commit 9121b15b5628b38b4695282dc18c553440e0f79b upstream.
Connecting to the backend isn't working reliably in xen-fbfront: in
case XenbusStateInitWait of the backend has been missed the backend
transition to XenbusStateConnected will trigger the connected state
only without doing the actions required when the backend has
connected.
