[ Upstream commit ee0017c3ed8a8abfa4d40e42f908fb38c31e7515 ]
If the driver detects that the controller is not ready before sending the first IOC facts command, it will wait for a maximum of 10 seconds for it to become ready. However, even if the controller becomes ready within 10 seconds, the driver will still issue a diagnostic reset.
Modify the driver to avoid sending a diag reset if the controller becomes ready within the 10-second wait time.
