#     
#     Pull clk fix from Stephen Boyd:
#      "A single fix for the clk framework that needed some more bake time in
#       linux-next.
#     
#       The problem is that two clks being registered at the same time can
#       lead to a busted clk tree if the parent isn't fully registered by the
#       time the child finds the parent. We rejigger the place where we mark
#       the parent as fully registered so that the child can't find the parent
#       until things are proper"
