[PATCH] libata: add dev->ap
Add dev->ap which points back to the port the device belongs to. This makes it unnecessary to pass @ap for silly reasons (e.g. printks). Also, this change is necessary to accomodate later PM support which will introduce ATA link inbetween port and device. Signed-off-by: Tejun Heo <htejun@gmail.com>
