If the device reports a hardware interrupt that has no mapping, irq_find_mapping() returns 0 and the handler of the system's IRQ 0 is invoked instead. Use generic_handle_domain_irq_safe(), which ignores unmapped hardware interrupts. Fixes: 51dad33ede63 ("mfd: Add core driver for Nuvoton NCT6694") Signed-off-by: Ming Yu --- Changes in v8: - New patch. Use generic_handle_domain_irq_safe() so that unmapped interrupts are ignored. drivers/mfd/nct6694.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/mfd/nct6694.c b/drivers/mfd/nct6694.c index de0027c98726..4f5a5b855de2 100644 --- a/drivers/mfd/nct6694.c +++ b/drivers/mfd/nct6694.c @@ -227,7 +227,7 @@ static void usb_int_callback(struct urb *urb) while (int_status) { int irq = __ffs(int_status); - generic_handle_irq_safe(irq_find_mapping(nct6694->domain, irq)); + generic_handle_domain_irq_safe(nct6694->domain, irq); int_status &= ~BIT(irq); } -- 2.34.1
