This is a note to let you know that I have just added a patch titled PCI: mvebu: Fix potential issue in range parsing to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 1fae89a762dd8b9ce8bc0950a3f75cb7b93bc9d5 Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot <jjhiblot@traphandler.com> Date: Fri, 14 Feb 2014 11:46:15 -0700 Subject: PCI: mvebu: Fix potential issue in range parsing commit 4f4bde1df33bde076f53325bdf2c6430cf85e1bb upstream. The second parameter of of_read_number() is not the index, but a size. As it happens, in this case it may work just fine because of the conversion to u32 and the favorable endianness on this architecture.
