From 18c25526c9cd4041e8e5acba811cffa606c175b7 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Wed, 4 May 2016 12:17:46 +0100 Subject: ia64/PCI: Fix incorrect PCI resource end address commit f976721e826e ("ia64/PCI: Use ioremap() instead of open-coded equivalent") introduced the following compiler warning, arch/ia64/sn/kernel/io_init.c: In function 'sn_io_slot_fixup': arch/ia64/sn/kernel/io_init.c:189:19: warning: 'addr' may be used uninitialized in this function [-Wmaybe-uninitialized] res->end = addr + size; ^ 'addr' is indeed uninitialised and the correct value to use is res->start.
