+From 159ccf0090f202cf031fa429df22e8b3f775ece8 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] drm/v3d: Set dma_mask as well as coherent_dma_mask
+
+Both coherent_dma_mask and dma_mask act as constraints on allocations
+and bounce buffer usage, so be sure to set dma_mask to the appropriate
+value otherwise the effective mask could be incorrect.
