[PATCH RESEND 26/27] Drivers: hv: utils: Invoke the poll function after handshake
When the handshake with daemon is complete, we should poll the channel since during the handshake, we will not be processing any messages. This is a potential bug if the host is waiting for a response from the guest. I would like to thank Dexuan for pointing this out. Signed-off-by: K. Y.
