I was referring to devices in the em28xx tree. In the case of the SAA7113 device, there really is no power saving feature unless a hardware pin is pulled down (or up I don't remember). The pin will basically reset the device. >>From my testing it seems like the power on defaults don't fully enable the device which is why I added the reinitialization to the s_power routine.
