Cc: Yoshinori Sato Cc: Rich Felker Cc: linux-sh@vger.kernel.org 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/sh/intc/userimask.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/drivers/sh/intc/userimask.c b/drivers/sh/intc/userimask.c index f9f043a3d90a..abe9091827cd 100644 --- a/drivers/sh/intc/userimask.c +++ b/drivers/sh/intc/userimask.c @@ -61,10 +61,18 @@ static DEVICE_ATTR(userimask, S_IRUSR | S_IWUSR, static int __init userimask_sysdev_init(void) { + struct device *dev_root; + int ret = 0; + if (unlikely(!uimask)) return -ENXIO; - return device_create_file(intc_subsys.dev_root, &dev_attr_userimask); + dev_root = bus_get_dev_root(&intc_subsys); + if (dev_root) { + ret = device_create_file(dev_root, &dev_attr_userimask); + put_device(dev_root); + } + return ret; } late_initcall(userimask_sysdev_init); -- 2.39.2
