[Qemu-devel] [RfC PATCH 4/5] usb/ehci: Guard definition of EHCI_DEBUG


From: Gerd Hoffmann
Subject: [Qemu-devel] [RfC PATCH 4/5] usb/ehci: Guard definition of EHCI_DEBUG
Date: Tue, 30 Oct 2012 12:28:41 +0100

From: Peter Crosthwaite <address@hidden>

Guard against re-definition of EHCI_DEBUG. Allows for turning on of debug info
from configure (using --qemu-extra-cflags="-DEHCI_DEBUG=1") rather than source
code hacking.
