Subject: [PATCH] Use pci_set_dma_mask() instead of direct assignment of DMA mask
X-Git-Tag: v2.6.13-rc1~48
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=cac8c81a59bd3b6815871b3172e8ccf15a3431e0;p=~emulex%2Finfiniband.git

[PATCH] Use pci_set_dma_mask() instead of direct assignment of DMA mask

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.

I do not own this device so I only compile-tested this patch.
