Cc: Thomas Gleixner Cc: Marc Zyngier Signed-off-by: Greg Kroah-Hartman --- Note, this is a patch that is a prepatory cleanup as part of a larger series of patches that is working on resolving some old driver core design mistakes. It will build and apply cleanly on top of 6.3-rc2 on its own, but I'd prefer if I could take it through my driver-core tree so that the driver core changes can be taken through there for 6.4-rc1. drivers/irqchip/irq-mbigen.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/drivers/irqchip/irq-mbigen.c b/drivers/irqchip/irq-mbigen.c index f3faf5c99770..30ca1bf7fc8b 100644 --- a/drivers/irqchip/irq-mbigen.c +++ b/drivers/irqchip/irq-mbigen.c @@ -245,11 +245,14 @@ static int mbigen_of_create_domain(struct platform_device *pdev, if (!of_property_read_bool(np, "interrupt-controller")) continue; - parent = platform_bus_type.dev_root; - child = of_platform_device_create(np, NULL, parent); - if (!child) { - of_node_put(np); - return -ENOMEM; + parent = bus_get_dev_root(&platform_bus_type); + if (parent) { + child = of_platform_device_create(np, NULL, parent); + put_device(parent); + if (!child) { + of_node_put(np); + return -ENOMEM; + } } if (of_property_read_u32(child->dev.of_node, "num-pins", -- 2.39.2
