[Qemu-devel] [PATCH 2/3] vl.c: Fold constant string into printf rather t

From: Michael Ellerman
Subject: [Qemu-devel] [PATCH 2/3] vl.c: Fold constant string into printf rather than using %s
Date: Mon, 12 Dec 2011 19:21:43 +1100

In help() we do what boils down to:

  printf("%s", "qemu");

This seems to be an artifact of be995c27640a82c7056b6f53d02ec823570114e5
("removed unused code"), which removed some ifdef'ery that used to print
a different name depending on CONFIG_SOFTMMU.

But now that is gone and we always use "qemu" we may as well just put
that in the format string.
