[Qemu-devel] [PATCH 06/24] Fix coding style issue

[Mark McLoughlin <markmc@redhat.com>]

Replace:

  if (-1 == foo())

with:

  if (foo() == -1)

While this coding style is not in direct contravention of our currently
ratified CODING_STYLE treaty, it could be argued that the Article 3 of
the European Convention on Human Rights (prohibiting torture and "inhuman
or degrading treatment") reads on the matter.
