Subject: vfio/pci: pass vector to virq functions
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d364d802fe4a5d73b2e88cb9b80799692f1ee8a5;p=thirdparty%2Fqemu.git

vfio/pci: pass vector to virq functions

Pass the vector number to vfio_connect_kvm_msi_virq and
vfio_remove_kvm_msi_virq, so it can be passed to their subroutines in
a subsequent patch.  No functional change.
