From: Radhesh Fadnis <[email protected]> In the context restore function, if the context is lost or not is being checked by the contents of the counter register. But this is logic hold good as long as counter reset value is zero, if the reset value is non-zero then above logic doesn't hold good. Hence removed checking of the register value and restoring the context.
