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.
