From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
Subject: [PATCH] palm_bk3710: use struct ide_port_info
* Factor out cable detection to palm_bk3710_cable_detect().
* Add palm_bk3710_init_hwif() (->init_hwif method implementation).
* Remove needless ->quirkproc initialization.
* Add missing ->pio_mask initialization.
* Use ATA_* defines for setting ->{ultra,mwdma}_mask.
* Add 'struct ide_port_info palm_bk3710_port_info' and pass it to
ide_device_add(). Then remove open-coded 'hwif' initialization.
