From: Bartlomiej Zolnierkiewicz Subject: [PATCH] ide: fix host drivers depending on ide_generic to probe for interfaces * Add mpc8xx_ide_probe() to mpc8xx.c and call it from probe_for_hwifs(). * Convert ide_arm, ide-cris, ide-h8300, ide-pnp, buddha, falconide, gayle, macide, q40ide, cmd640 and mpc8xx host drivers to use ide_device_add(). This removes dependency on ide_generic for these drivers so update ide/Kconfig accordingly.
