Subject: [PATCH] qxl: avoid an oops in the deferred io code.
Date: Mon, 4 Nov 2013 16:39:27 +1000 [thread overview]
Message-ID: <1383547167-1161-1-git-send-email-airlied@gmail.com> (raw)
From: Dave Airlie <airlied@redhat.com>
If we are using deferred io due to plymouth or X.org fbdev driver
we will oops in memcpy due to this pointless multiply here,
removing it fixes fbdev to start and not oops.
