Subject: [PATCH 0/3] vfio: Fix coverity found issues

Overall nothing very serious here.  We botch the size of a PCIe
capability due to a cut-n-paste error, but nobody has noticed due to
the rarity of the capability.  A 32bit host could possibly see some
overflows attempting to do a DMA map, but all of the parameters are
also validated elsewhere, so while this may cause unexepected behavior
for the user, there doesn't appear to be any risk to the host.
Thanks,

Alex
