ide: add struct ide_port_ops (take 2)
* Move hooks for port/host specific methods from ide_hwif_t to 'struct ide_port_ops'. * Add 'const struct ide_port_ops *port_ops' to 'struct ide_port_info' and ide_hwif_t. * Update host drivers and core code accordingly. While at it: * Rename ata66_*() cable detect functions to *_cable_detect() to match the standard naming. (Suggested by Sergei Shtylyov) v2: * Fix build for bast-ide. (Noticed by Andrew Morton) Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
