The patch looks ok, but the SS_DEBOUNCE thing is horrible.

Why do it? All of the SS_DETECT logic is inside cs.c anyway. Now you
introduce SS_DEBOUNCE to fix a cs.c bug, and "export" that cs.c logic bug
into the low-level driver.

An alternative, and probably more logical, fix is much simpler: add a

socket->events = 0;

to "yenta_get_status()". Nothing more, nothing less.

Why? Because the whole point of the socket->handler() callback is to tell
the cs layer that something new happened. But if the cs layer already did
a "get_status()", then obviously the event is no longer "new". So it
should be cleared out.


Also, I'd be a lot happier just changing all timeouts to microseconds.
"centiseconds" really don't exist as a valid amount of time.
