Sakari Ailus 854c14b2a1 ACPI: Get acpi_device's parent from the parent field ... commit 9054fc6d57e80c27c0b0632966416144f2092c2b upstream. Printk modifier %pfw is used to print the full path of the device name. This is obtained device by device until a device no longer has a parent. On ACPI getting the parent fwnode is done by calling acpi_get_parent() which tries to down() a semaphore. But local IRQs are now disabled in vprintk_store() before the mutex is acquired. This is obviously a problem. Luckily struct device, embedded in struct acpi_device, has a parent field already. Use that field to get the parent instead of relying on acpi_get_parent().
