From 5f53624662eaac89598641cee6cd54fc192572d9 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 10 Apr 2018 15:21:43 +0200 Subject: ARM: amba: Make driver_override output consistent with other buses 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)".
