Non-DT board code like for instance board-kzm9d.c needs to operate of a static IRQ range for platform devices. So this patch is updating the code to make use of the function irq_domain_add_simple() instead of irq_domain_add_linear(). Fixes a EMEV2 / KZM9D runtime error caused by the following commit: 7385500 gpio/em: convert to linear IRQ domain Cc: stable@kernel.org Signed-off-by: Magnus Damm Tested-by: Simon Horman Reported-by: Simon Horman Signed-off-by: Linus Walleij --- diff --git a/drivers/gpio/gpio-em.c b/drivers/gpio/gpio-em.c index bdc8302e711a..deca78f99316 100644 --- a/drivers/gpio/gpio-em.c +++ b/drivers/gpio/gpio-em.c @@ -299,8 +299,9 @@ static int em_gio_probe(struct platform_device *pdev) irq_chip->irq_set_type = em_gio_irq_set_type; irq_chip->flags = IRQCHIP_SKIP_SET_WAKE; - p->irq_domain = irq_domain_add_linear(pdev->dev.of_node, + p->irq_domain = irq_domain_add_simple(pdev->dev.of_node, pdata->number_of_pins, + pdata->irq_base, &em_gio_irq_domain_ops, p); if (!p->irq_domain) { ret = -ENXIO;
