[Qemu-commits] [COMMIT fa0cfdf] vnc: Set invalid buffer pointers to NULL

From: Anthony Liguori
Subject: [Qemu-commits] [COMMIT fa0cfdf] vnc: Set invalid buffer pointers to NULL
Date: Mon, 05 Oct 2009 14:53:34 -0000

From: Stefan Weil <address@hidden>

After qemu_free, the pointers for input and output
buffers are no longer valid, so set them to NULL
(most other calls of qemu_free in vnc.c use this
pattern, too).
