[PATCH 03/14] MIPS: adapt for dma_map_ops changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



From: Andrzej Pietrasiewicz <andrzej.p@xxxxxxxxxxx>

Adapt core MIPS architecture code for dma_map_ops changes: replace
alloc/free_coherent with generic alloc/free methods.
