From 5de267b299829b99990305ad0440753bb8aa3de2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 11 Jan 2017 14:41:40 +0100 Subject: [PATCH] ARM: mv78xx0: fix possible PCI buffer overflow gcc-7.0 reports a potential array overflow: arch/arm/mach-mv78xx0/pcie.c: In function 'mv78xx0_pcie_preinit': arch/arm/mach-mv78xx0/pcie.c:81:4: error: output may be truncated before the last format character [-Werror=format-truncation=] I haven't checked if this can actually happen, but making the array one 32-bit word longer addresses the warning and makes it completely safe.
