From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Wed, 11 Jan 2017 14:41:40 +0100 Subject: [PATCH] ARM: mv78xx0: fix possible PCI buffer overflow Message-ID: <20170111134159.3832518-1-arnd@arndb.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
