+Subject: [PATCH 176/224] clk: mediatek: Fix all warnings for missing struct
+ clk_onecell_data
+
+Even though the header file linux/clk-provider.h is already being properly
+included in clk-mtk.h, the definition of struct clk_onecell_data still
+must depend on CONFIG_COMMON_CLK defined and thus it's possible that
+below build warnings occur when CONFIG_COMMON_CLK is not being selected.
+
+Therefore, these functions which need struct clk_onecell_data without
+declaring that structure first requires simply declaring that this struct
+exists prior to referencing it in clk-mtk.h
+
+Changes from v1->v2:
+enhance v1 based on two useful solutions Jean Delvare kindly suggested.
+
+All warnings (new ones prefixed by >>):

+In file included from drivers/clk/mediatek/reset.c:22:0:
