[Qemu-devel] [PATCH 06/15] VNC: Fix memory allocation (wrong structure size).

[Glauber Costa]

From: Stefan Weil <address@hidden>

Pointer vs addresses a VncDisplay structure,
so it is sufficient to allocate sizeof(VncDisplay)
or sizeof(*vs) bytes instead of the much larger
sizeof(VncState).

Maybe the misleading name should be fixed, too:
the code contains many places where vs is used,
sometimes it is a VncState *, sometimes it is a
VncDisplay *. vd would be a better name.
