[PATCH] libata: implement ata_dev_disable()
This patch implements ata_dev_disable() which prints a warning message and takes @dev offline. Currently, this is done by explicitly incrementing dev->class with case-by-case warning messages. Giving user clear indication when libata gives up will be more important as libata will be doing more retries. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
