This is a note to let you know that I have just added a patch titled KVM: return an error code in kvm_vm_ioctl_register_coalesced_mmio() to the linux-3.5.y-queue branch of the 3.5.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-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 117532deff350eb48253ad5b872fae535c987bbf Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@oracle.com> Date: Wed, 29 Jan 2014 16:16:39 +0300 Subject: KVM: return an error code in kvm_vm_ioctl_register_coalesced_mmio() commit aac5c4226e7136c331ed384c25d5560204da10a0 upstream. If kvm_io_bus_register_dev() fails then it returns success but it should return an error code. I also did a little cleanup like removing an impossible NULL test.
