From 75e50217c8c8d9ab8dc84547fd149d9bfe32ae5d 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.
