[SMC911x ]fix for driver resume and compilation warning

Hi,
     I am trying out suspend, resume on an OMAP3 based board. What I see during resume is that the SMC911x driver resume routing gets stuck after trying to transmit the packet out of the controller. Some debug messages below:

--> smc911x_drv_resume
eth0: --> smc911x_reset
eth0: smc911x_reset timeout waiting for PM restore
eth0: --> smc911x_enable

The following change makes it work fine: (The change within smc911x_drv_probe function was to get rid of a compilation warning).
Additionally, the SMC9211 data sheet says that when we enter D2 sleep state, we need to set the EDPWRDOWN bit in the PHY Mode control/status register and clear it when we are back to D0. This is not done in the code as far as I can see. So does it mean that the PHY is not powered down but the controller is? I have another patch that fixes it. I will send that as well unless I am missing something.

Thanks,
