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.
