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!

Caused by commits

d1506b749e92 ("clk: qcom: support for alpha pll properties")
e66a4d6d0081 ("clk: qcom: support for dynamic updating the PLL")
301803e6013b ("clk: qcom: support Huayra type Alpha PLL")

Yep. I'll export the regs and remove the clk_hw_is_enabled()
usage. Should be possible to do that inside the ops directly
instead of going through the framework for it.

Thanks Stephen for updating the patches :-)

Correct. clk_alpha_pll_is_enabled can do that.
