From: FUJITA Tomonori Date: Mon, 12 Apr 2010 14:32:11 +0000 (+0000) Subject: chelsio: use the DMA state API instead of the pci equivalents X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=094f92a61aa044142c231e04c35c00a9cc70adbc;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git chelsio: use the DMA state API instead of the pci equivalents This replace the PCI DMA state API (include/linux/pci-dma.h) with the DMA equivalents since the PCI DMA state API will be obsolete. No functional change. For further information about the background: http://marc.info/?l=linux-netdev&m=127037540020276&w=2 Signed-off-by: FUJITA Tomonori Cc: Divy Le Ray Signed-off-by: David S.
