| Subject: drm/ast: Fix HW cursor image |
| |
| From: Benjamin Herrenschmidt <benh@kernel.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. |
