Subject: via82cxxx: keep local ide_pci_device_t copy
X-Git-Tag: v2.6.24-rc1~128^2~23
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6157332edabdf77ccae2a033b53bbc9ae1d70ede;p=linux-2.6

via82cxxx: keep local ide_pci_device_t copy

* Keep local ide_pci_device_t copy in via_init_one().

* Adjust ide_pci_device_t copy according to id->driver_data in via_init_one()
  and remove no longer needed second via82cxxx_chipsets[] entry.

* via82cxxx_chipsets[] -> via82cxxx_chipset.

* Remove IDE_HFLAGS_VIA define.

* Bump driver version.
