2014-02-26pci-assign: Fix potential read beyond buffer on -EBUSYMarkus Armbruster1-0/+1
readlink() doesn't write a terminating null byte. assign_failed_examine() passes the unterminated string to strrchr(). Oops. Terminate it. Spotted by Coverity.

2013-11-13pci-assign: Fix error_report of pci-stub messageCole Robinson1-20/+16
Using multiple calls to error_report here means every line is prefaced with the (potentially long) pci-assign command line arguments. Use a single error_printf to preserve the intended formatting. Since this code path is always preceded by an error_report call, we don't lose the command line reporting.

2013-11-07pci-assign: Remove dead code for direct I/O region access from userspaceJan Kiszka1-46/+10
This feature was already deprecated back then in qemu-kvm, ie. before pci-assign went upstream. assigned_dev_ioport_rw will never be invoked with resource_fd < 0.
