[Qemu-commits] [COMMIT 387f4a5] hw/serial: don't create a char device if

From: Anthony Liguori
Subject: [Qemu-commits] [COMMIT 387f4a5] hw/serial: don't create a char device if none isspecified
Date: Mon, 14 Sep 2009 23:24:44 -0000

From: Aurelien Jarno <address@hidden>

When creating null devices, there is no way to ensure the unicity of
the labels. Bail out with an error message instead.
