[PATCH 3.13 081/105] drm/ast: Fix HW cursor image

[Kamal Mostafa]

3.13.11.10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>

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.
