I just ran into a similar problem when moving the Yocto MIPS reference
board from 3.8 --> 3.10.  It is caused by this commit added in 3.9:

   ------------------------------
   commit f9a8f83b04e0c362a2fc660dbad980d24af209fc
   Author: Florian Fainelli <florian@openwrt.org>
   Date:   Mon Jan 14 00:52:52 2013 +0000

       net: phy: remove flags argument from phy_{attach, connect, connect_direct}

       The flags argument of the phy_{attach,connect,connect_direct} functions
       is then used to assign a struct phy_device dev_flags with its value.
       All callers but the tg3 driver pass the flag 0, .....
   ------------------------------

I wonder if you removed the right argument, since that is all I did
for the Yocto board, and it was happy...

Paul.
