[Xen-devel] [PATCH 2/3] xen/events: remove unnecessary call to bind_evtchn_to_cpu()

[David Vrabel <david.vrabel@xxxxxxxxxx>]

From: David Vrabel <david.vrabel@xxxxxxxxxx>

Since bind_evtchn_to_cpu() is always called after an event channel is
bound, there is no need to call it after closing an event channel.
