[Qemu-devel] [PULL 2.3 5/5] powerpc: fix -machine usb=no for newworld an


From: Alexander Graf
Subject: [Qemu-devel] [PULL 2.3 5/5] powerpc: fix -machine usb=no for newworld and pseries machines
Date: Wed, 25 Mar 2015 22:55:00 +0100

From: Paolo Bonzini <address@hidden>

Capture the explicit setting of "usb=no" into a separate bool, and
use it to skip the update of machine->usb in the board init function.
