Message-Id: <20131202191258.460929986@linuxfoundation.org> Date: Mon, 2 Dec 2013 11:14:50 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Dave Airlie <airlied@...hat.com> Subject: [PATCH 3.12 099/212] qxl: avoid an oops in the deferred io code. 3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dave Airlie <airlied@...hat.com> commit cc87509d87696d7cd393882f5dedea01e03e41a9 upstream. 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.
