You don't need this cast because of_get_property() returns  
void *.


Stephen,

True. But without this gcc complains:

CC [M]  drivers/net/ucc_geth.o
drivers/net/ucc_geth.c: In function bucc_geth_probeb:
drivers/net/ucc_geth.c:3824: warning: assignment discards

from pointer target type


ph should be declared const phandle *.  Look at other uses of
of_get_property.



Ok fine. Here is a revised patch again.

Is there anything else to be done in this patch. If this is OK, can  
this

be applied. I am not sure, but, i find Li Yang as the maintainer for
this in linux*/MAINTAINERS file. Kindly let me know if this patch

Li,

Any thoughts on this patch ?

Yeah, this is not the right fix.  The SGMII change doesn't mesh well
with the of_mdio changes and needed some rewriting.  I'm about to post
a patch (compile tested only) which should make things happy.
