4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert+rene...@glider.be>
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)".
