Subject: [PATCH] KVM: selftests: Use proper function prototypes in probing
 code
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Make the main() functions in the probing code proper prototypes so that
compiling the probing code with more strict flags won't generate false
negatives.

  <stdin>:1:5: error: function declaration isn’t a prototype [-Werror=strict-prototypes]
