Hi Greg,

Here are fixes for a few regressions that came in with my
carelessness with the irq latency work for the hvc subsystem.
These were independently reported in 2 configurations, and I
confirmed with another.

I think those went upstream via Michael's tree, but he's away
at the moment so if you would be able to consider them for
the tty tree that would be appreciated.

Thanks,
Nick
