Msi_chip functions setup_irq/teardown_irq rarely use msi_chip
argument.

That's not true. Out of the four drivers that you modify two use the
parameter. And the two that don't probably should be using it too.

50% is not "rarely". =)

          We can look up msi_chip pointer by the device pointer
or irq number, so clean up msi_chip argument.

I don't like this particular change. The idea was to keep the API object
oriented so that drivers wouldn't have to know where to get the MSI chip
from. It also makes it more resilient against code reorganizations since
the core code is the only place that needs to know where to get the chip
from.

Hm, ok, Thomas also don't like this change, I will drop this one, thanks.

Thanks!
