KVM: Clean up kvm_vm_ioctl_assigned_device
Any arch not supporting device assigment will also not build assigned-dev.c. So testing for KVM_CAP_DEVICE_DEASSIGNMENT is pointless. KVM_CAP_ASSIGN_DEV_IRQ is unconditinally set. Moreover, add a default case for dispatching the ioctl. Acked-by: Alex Williamson <alex.williamson@redhat.com> Acked-by: Michael S.
