Subject: [PATCH] net/sis900: Use the DMA_32BIT_MASK constant
X-Git-Tag: v2.6.13-rc1~83
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12b279f9c0cb70695865dc336161512fa6e75d50;p=linux-2.6

[PATCH] net/sis900: Use the DMA_32BIT_MASK constant

Use the DMA_32BIT_MASK constant from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask() instead of custom
macros.
This patch includes dma-mapping.h explicitly because it caused errors
on some architectures otherwise.
See http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for details
