Mauro,

I didn't review your patch yet, and it needs to be tested, however,
the bug reported in this thread deals with the same regression that
you are attempting to repair, but on the cx88 driver -- not the
saa7134 driver.

Both drivers need to be tested to make sure that this regression has been fixed.
