  Thanks Stephen for your great help and support.
  It seems, we are getting the error in the following error with these
  patches because of missing EXPORT_SYMBOL_GPL for
  clk_alpha_pll_regs and clk_hw_is_enabled.


ERROR: "clk_alpha_pll_regs" [drivers/clk/qcom/mmcc-msm8996.ko] 
undefined!

ERROR: "clk_hw_is_enabled" [drivers/clk/qcom/clk-qcom.ko] undefined!
