Subject: hw/pci/msi: Restrict xen_is_pirq_msi() call to Xen
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ede601a61fd4053481920fb644f495d01a6861a1;p=users%2Fdwmw2%2Fqemu.git

hw/pci/msi: Restrict xen_is_pirq_msi() call to Xen

Similarly to the restriction in hw/pci/msix.c (see commit
e1e4bf2252 "msix: fix msix_vector_masked"), restrict the
xen_is_pirq_msi() call in msi_is_masked() to Xen.
