[PATCH 9/20] [powerpc,cell] Constify & voidify get_property()
Jeremy Kerr

Tue Jul 4 16:46:44 EST 2006
Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.
cell platform changes.
Built for cell_defconfig
