Subject: virtio_balloon: fix sparse warning
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8875bbba97087bf4a677071723d04fc00730f1e7;p=linux.git

virtio_balloon: fix sparse warning

balloon uses virtio32_to_cpu instead of cpu_to_virtio32
to convert a native endian number to virtio.
No practical difference but makes sparse warn.
Fix it up.
