[PATCH 05/12] kvm: qemu: device-assignment: fixup error reporting

[Mark McLoughlin]

If kvm_assign_pci_device(), there's no need for us to print
two lines of error messages. The string translation of errno
is very useful though, so include that in the message using
strerror().

[PATCH 12/12] kvm: qemu: device-assignment: init_assigned_device() error handling

[Mark McLoughlin]

Associate the AssignedDevice with the AssignedDevInfo as soon as
we have allocated it and don't try and free it in init_assigned_device()
if an error occurs.

This ensures that the mmio region is unmapped by free_assigned_device()
if init_assigned_device() fails.

Um, that's a rather embarrassing thinko.

Re: [PATCH 01/12] kvm: qemu: device-assignment: add_assigned_device() returns a pointer

[Mark McLoughlin]

Hi Avi,

Sorry ... forgot to 'git send-email --compose' :-)

The patchset is just a bunch of fixes to the device-assignment error
handling code. Shouldn't be anything too controversial there.

Cheers,
Mark.

No, all applied.  Patch 2 looks like two patches munged together; I 
applied it anyway as it wasn't worth the effort to respin.
