Subject: PCI: shrink pci_dev_info's is_extfn/is_virtfn members
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=51bfd20efaf85ec408998ba06b17d5e73d12537e;p=xen.git

PCI: shrink pci_dev_info's is_extfn/is_virtfn members

They are used as boolean flags only, so convert them accordingly
(shrinking the structure size by 8 bytes).
