Subject: ide_4drives: use struct ide_port_info
X-Git-Tag: v2.6.27-rc1~1049^2~47
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f333f92bf9040fb63d13c184295629c7a0ff449f;p=linux-2.6-omap-h63xx.git

ide_4drives: use struct ide_port_info

Convert the driver to use struct ide_port_info - as a nice side-effect
this fixes hwif->channel initialization.
