From 2855568b1ee4f58ef2c0a13ddfceb4b0b216b7ed Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 11 Oct 2007 17:12:35 -0400 Subject: [PATCH] [libata] struct pci_dev related cleanups * remove pointless pci_dev_to_dev() wrapper. Just directly reference the embedded struct device like everyone else does. * pata_cs5520: delete cs5520_remove_one(), it was a duplicate of ata_pci_remove_one() * linux/libata.h: don't bother including linux/pci.h, we don't need it. Simply declare 'struct pci_dev' and assume interested parties will include the header, as they should be doing anyway. * linux/libata.h: consolidate all CONFIG_PCI declarations into a single location in the header.
