4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Geert Uytterhoeven <[email protected]> commit 5f53624662eaac89598641cee6cd54fc192572d9 upstream. For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices. Make AMBA consistent with other buses by dropping the test for a NULL pointer. Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)".
