Subject: ide: set hwif->dev in ide_init_port_hw() (take 2)
X-Git-Tag: v2.6.27-rc1~1049^2~49
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c56c5648a3bd15ff14c50f284b261140cd5b5472;p=pandora-kernel.git

ide: set hwif->dev in ide_init_port_hw() (take 2)

* Add 'parent' field to hw_regs_t for optional parent device pointer (needed
  by macio PMAC IDE controllers) and set hwif->dev in ide_init_port_hw().

* Update au1xxx-ide.c, sgiioc4.c, pmac.c and setup-pci.c accordingly.

v2:

* Update scc_pata.c.

There should be no functional changes caused by this patch.
