Subject: [PATCH 0/9] Make clk_hw::init NULL after clk registration

We don't want clk provider drivers using the init member of struct
clk_hw after the clk is registered. It isn't guaranteed to be a valid
pointer and all the necessary information inside the structure is copied
over into struct clk_core anyway. This patch series fixes up the handful
of users that do this and then overwrites the pointer to NULL within the
clk registration path.

Stephen Boyd (9):
  clk: actions: Don't reference clk_init_data after registration
  clk: lochnagar: Don't reference clk_init_data after registration
  clk: meson: axg-audio: Don't reference clk_init_data after
    registration
  clk: qcom: Don't reference clk_init_data after registration
  clk: sirf: Don't reference clk_init_data after registration
  clk: socfpga: Don't reference clk_init_data after registration
  clk: sprd: Don't reference clk_init_data after registration
  phy: ti: am654-serdes: Don't reference clk_init_data after
    registration
  clk: Overwrite clk_hw::init with NULL during clk_register()
