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/irqchip/irq-mips-cpu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -u -p a/drivers/irqchip/irq-mips-cpu.c b/drivers/irqchip/irq-mips-cpu.c --- a/drivers/irqchip/irq-mips-cpu.c +++ b/drivers/irqchip/irq-mips-cpu.c @@ -154,7 +154,7 @@ asmlinkage void __weak plat_irq_dispatch static int mips_cpu_intc_map(struct irq_domain *d, unsigned int irq, irq_hw_number_t hw) { - static struct irq_chip *chip; + struct irq_chip *chip; if (hw < 2 && cpu_has_mipsmt) { /* Software interrupts are used for MT/CMT IPI */
