Subject: b44: Use kernel DMA addresses for the kernel DMA API
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=37efa239901493694a48f1d6f59f8de17c2c4509;p=linux-2.6-omap-h63xx.git

b44: Use kernel DMA addresses for the kernel DMA API

We must not use the device DMA addresses for the kernel DMA API, because
device DMA addresses have an additional offset added for the SSB translation.

Use the original dma_addr_t for the sync operation.
