From 5589818b2fab09c4b7250865a6163c3e2f81a9d6 Mon Sep 17 00:00:00 2001 From: Sean Wang Date: Mon, 25 Dec 2017 16:03:57 +0800 Subject: 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: >>drivers/clk/mediatek/clk-mtk.h:44:19: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration int num, struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:63:19: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration int num, struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:145:10: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:164:11: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:190:12: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ Reported-by: kbuild test robot Signed-off-by: Sean Wang Cc: kbuild-all@01.org Cc: Stephen Boyd Cc: Jean Delvare Cc: linux-clk@vger.kernel.org Signed-off-by: Stephen Boyd --- drivers/clk/mediatek/clk-mtk.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/clk') diff --git a/drivers/clk/mediatek/clk-mtk.h b/drivers/clk/mediatek/clk-mtk.h index f10250dcece4..bf8006d41861 100644 --- a/drivers/clk/mediatek/clk-mtk.h +++ b/drivers/clk/mediatek/clk-mtk.h @@ -20,6 +20,7 @@ #include struct clk; +struct clk_onecell_data; #define MAX_MUX_GATE_BIT 31 #define INVALID_MUX_GATE_BIT (MAX_MUX_GATE_BIT + 1) -- cgit v1.2.3
