[Qemu-devel] [PATCH 1.1] qapi: QMP input visitor, handle floats parsed as ints

[Michael Roth]

JSON numbers can be interpreted as either integers or floating point
values depending on their representation. As a result, QMP input visitor
might visit a QInt when it was expecting a QFloat, so add handling to
account for this.
