Subject: libata: move ata_pci_default_filter() out of CONFIG_PCI
X-Git-Tag: v2.6.26-rc1~1150^2~60
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=071ce34d57924edb76b76f7de460eb4991463959;p=linux-2.6

libata: move ata_pci_default_filter() out of CONFIG_PCI

ata_pci_default_filter() doesn't really have anything to do with PCI.
It's generally applicable to BMDMA controllers.  Move it out of
CONFIG_PCI.
