Subject: virhostdev.c: add virHostdevIsPCIDevice() helper
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=a8017c688275f7bfee5eb70e03bc9549c746ccdd;p=libvirt.git

virhostdev.c: add virHostdevIsPCIDevice() helper

Add a helper to quickly determine if a hostdev is a PCI device,
instead of doing a tedious 'if' check with hostdev mode and
subsys type.
