mfd: Use the AB8500's IRQ domain to convert hwirq to virq
Before the AB8500 had its own IRQ domain, the IRQ handler would take the fired local IRQ (hwirq) and add it to the irq_base to convert it to an IRQ number which Linux would understand (virq). However, the IRQ base is not always used anymore since we can make use of Linear domains. It's better to use the AB8500 hwirq -> virq mapping helper function to convert them instead. That's what we do here. Signed-off-by: Lee Jones <lee.jones@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
