Subject: linux-4.1-rc7/drivers/irqchip/irq-renesas-intc-irqpin.c:418: array
 index used before limits check ?

Hello there,

[linux-4.1-rc7/drivers/irqchip/irq-renesas-intc-irqpin.c:418]: (style) Array ind
ex 'k' is used before limits check.

   if (!io[k] && k < INTC_IRQPIN_REG_NR_MANDATORY) {

Suggest sanity check array index before use.

Regards

David Binderman
