From c59a3da1342ff456e5123361739bc331446cda21 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Fri, 15 Dec 2006 13:57:26 -0800 Subject: IB: Fix ib_dma_alloc_coherent() wrapper The ib_dma_alloc_coherent() wrapper uses a u64* for the dma_handle parameter, unlike dma_alloc_coherent, which uses dma_addr_t*. This means that we need a temporary variable to handle the case when ib_dma_alloc_coherent() just falls through directly to dma_alloc_coherent() on architectures where sizeof u64 != sizeof dma_addr_t.
