Subject: [PATCH 1/9] rt2x00: Move Move pci_dev specific access to rt2x00pci
|
|
|
|
pci_dev->irq and pci_name(pci_dev) access should be limited
|
|
to rt2x00pci only. This is more generic and allows a rt2x00 pci
|
|
driver to be controlled as PCI device but also as platform driver
|
|
(needed for rt2800pci SoC support).
