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. arch/sh/drivers/dma/dma-sysfs.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/arch/sh/drivers/dma/dma-sysfs.c b/arch/sh/drivers/dma/dma-sysfs.c index 8ef318150f84..431bc18f0a41 100644 --- a/arch/sh/drivers/dma/dma-sysfs.c +++ b/arch/sh/drivers/dma/dma-sysfs.c @@ -45,13 +45,19 @@ static DEVICE_ATTR(devices, S_IRUGO, dma_show_devices, NULL); static int __init dma_subsys_init(void) { + struct device *dev_root; int ret; ret = subsys_system_register(&dma_subsys, NULL); if (unlikely(ret)) return ret; - return device_create_file(dma_subsys.dev_root, &dev_attr_devices); + dev_root = bus_get_dev_root(&dma_subsys); + if (dev_root) { + ret = device_create_file(dev_root, &dev_attr_devices); + put_device(dev_root); + } + return ret; } postcore_initcall(dma_subsys_init);
