   4 Subject: [PATCH 176/224] clk: mediatek: Fix all warnings for missing struct
   5  clk_onecell_data
   6
   7 Even though the header file linux/clk-provider.h is already being properly
   8 included in clk-mtk.h, the definition of struct clk_onecell_data still
   9 must depend on CONFIG_COMMON_CLK defined and thus it's possible that
  10 below build warnings occur when CONFIG_COMMON_CLK is not being selected.
  11
  12 Therefore, these functions which need struct clk_onecell_data without
  13 declaring that structure first requires simply declaring that this struct
  14 exists prior to referencing it in clk-mtk.h
  15
  16 Changes from v1->v2:
  17 enhance v1 based on two useful solutions Jean Delvare kindly suggested.
