Subject: drm/ast: Fix HW cursor image
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.
