Sorry for being so long to test, I was a bit busy.

The pcf8574 driver works correctly, ie as before. I think you can merge 
the patch.

The pcf8591 driver does not work, ie it does not detect the chip. I 
don't know if it is a problem on my side or of the driver, I will try to 
investigate the problem this evening.
