[Qemu-devel] [PATCH 3/9] qga: fix false negative argument passing

[arei.gonglei]

From: Gonglei <arei.gong...@huawei.com>

Function send_response(s, &qdict->base) returns a negative number
when any faliures occured. But strerror()'s parameter cannot be
negative. Let's change the testing condition and pass '-ret' to
strerr().
