Drivers: hv: Get rid of the unused global signaling state
Now that we have implemented a per-connection signaling mechanism, get rid of the global signaling state. For hosts that don't support per-connection signaling handle, we have moved the global state to be a per-channel state. Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Reviewed-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
