Message-Id: <1414436240-13879-82-git-send-email-kamal@canonical.com> Date: Mon, 27 Oct 2014 11:56:56 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Benjamin Herrenschmidt <benh@...nel.crashing.org>, Dave Airlie <airlied@...hat.com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.13 081/105] drm/ast: Fix HW cursor image 3.13.11.10 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Benjamin Herrenschmidt <benh@...nel.crashing.org> commit 1e99cfa8de0f0879091e33cd65fd60418d006ad9 upstream. The translation from the X driver to the KMS one typo'ed a couple of array indices, causing the HW cursor to look weird (blocky with leaking edge colors). This fixes it.
