[netdrvr] smc911x: fix for driver resume (and compilation warning)

Browse Source 
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
eth0: --> smc911x_phy_configure()
eth0: --> smc911x_phy_reset()
eth0: phy caps=0x782d

smc911x_phy_read: phyaddr=0x1, phyreg=0x01, phydata=0x7809

The following change makes it work fine: (The change within
smc911x_drv_probe function was to get rid of a compilation warning).
