Subject: vfio/igd: remove unsupported device ids
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8492a6129c3c581cd6f94a0c11e9c4c5ebbac9dc;p=qemu.git

vfio/igd: remove unsupported device ids

Since e433f208973f ("vfio/igd: return an invalid generation for unknown
devices"), the default return of igd_gen() was changed to unsupported.
There is no need to filter out those unsupported devices.
