Subject: [PATCH 6/8] ide: separate PCI specific init from generic init in ide_pci_setup_ports()
Date: Sun, 06 Jan 2008 18:03:03 +0100	[thread overview]
Message-ID: <20080106170303.6861.43285.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20080106170220.6861.4814.sendpatchset@localhost.localdomain>

* Setup ->mate and ->channel in ide_pci_setup_ports() instead of
  in ide_hwif_configure().

* Make 'port' parameter for ide_hwif_configure() 'unsigned int'.

* Separate PCI specific init from generic init in ide_pci_setup_ports().
