Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- These patches are all independent of each other. drivers/clk/clk-moxart.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff -u -p a/drivers/clk/clk-moxart.c b/drivers/clk/clk-moxart.c --- a/drivers/clk/clk-moxart.c +++ b/drivers/clk/clk-moxart.c @@ -18,7 +18,7 @@ static void __init moxart_of_pll_clk_init(struct device_node *node) { - static void __iomem *base; + void __iomem *base; struct clk_hw *hw; struct clk *ref_clk; unsigned int mul; @@ -57,7 +57,7 @@ CLK_OF_DECLARE(moxart_pll_clock, "moxa,m static void __init moxart_of_apb_clk_init(struct device_node *node) { - static void __iomem *base; + void __iomem *base; struct clk_hw *hw; struct clk *pll_clk; unsigned int div, val;
