[Xen-devel] [PATCH] Wait the state Connect of the frontend before connect the backend.

[anthony.perard@xxxxxxxxxx]

From: Anthony PERARD <anthony.perard@xxxxxxxxxx>

The frontend of the framebuffer set a value (request-abs-pointer) and go
to the state Connected.  The backend must read this value only when the
frontend has the state Connected.
