[PATCH 05/51] DMA-API: net: intel/igbvf: fix 32-bit DMA mask handling

2013-09-20 Thread Russell King
The fallback to 32-bit DMA mask is rather odd: err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)); if (!err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64)); if (!err) pci_using_dac = 1; } else {
