From e93d8210c7769e4cac59f2430ba81589a76ca5e5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 3 Aug 2018 16:38:44 +0200 Subject: [PATCH] PCI: mvebu: Fix I/O space end address calculation [ Upstream commit dfd0309fd7b30a5baffaf47b2fccb88b46d64d69 ] pcie->realio.end should be the address of last byte of the area, therefore using resource_size() of another resource is not correct, we must substract 1 to get the address of the last byte.
